Rattrap is a Maximal who turned into a Giant Rat from the Beast Wars Transformers universe, an infiltrator, sharpshooter, saboteur and demolitions expert. An unflinching pessimist, he is famous for delivering the line “We're all gonna die!.” when things look grim for the Maximals, which usually reacted the immediate response from his fellow Maximals: “Shut up, Rattrap!”; barring two instances: once in the episode "Coming of the Fuzors Pt. 2", to which Rhinox replies, "It happens" and once in the series finale "Nemesis pt 2": after Megatron used the ancient Decepticon battleship Nemesis to uncover the resting place of the Ark. The only response was a grim "Yep" from Rhinox. After delivering the line in a Season 2 episode, he follows it with "I know, I know. 'Shut up, Rattrap.'" In the episode “Dark Voyage” he mentioned that he used to be an energon miner. It is humorously suggested in the show that he is a distant relative of Autobot Arcee ("What in the name of my great-aunt Arcee is going on here?!" "Transmutate"). Although never seen in the television series, a toy of him from the 2006 Botcon says he turned into a Cybertronian motorcycle before being reformatted as a rat. From what we know of his past life on Cybertron, he was a gambler, a womanizer and spent his free time at bars, referenced in his comment to Silverbolt concerning a place in which the servant bots walk around "minus their torso plates" ("The Agenda" Part 1). Rattrap is the most eager of the Maximals to return home.

Second to Rhinox, Rattrap has some knowledge about mechanics, especially sabotage and demolition/explosives, managing to create an effective countermeasure to Tarantulas's shield around a Vok ship in one episode. Rattrap often criticizes Cheetor's immaturity and stupidity and at times defies Optimus Primal when he feels Optimus's ideas are unreasonable, too risky or stupid. Rattrap also expresses frequent suspicions of Dinobot's loyalty throughout his time as a Maximal. For his part, Dinobot never likes Rattrap either, often referring to him as "vermin" and making jokes about Rattrap's odor. Though the two often bicker, their relationship evolves over time and they become friendly rivals right up until the time of Dinobot's betrayal in "Maximal, No More". Although Rattrap never quite trusts him after Dinobot's brief return to his original Predacon allegiance, it is Rattrap who is shown to be the most affected by Dinobot's bravery and passing as Dinobot lay dying in Code of Hero. After Dinobot's death, Rattrap is often partnered with the fuzor Silverbolt. The consummate wisecracker, he is constantly giving his comrades nicknames, both derogatory and friendly. Despite his tendency to give his comrades nicknames, Rattrap is, in fact, capable of being leader, and has more than once, in Primal's absence takes the mantle of leadership, albeit reluctantly (Chain of Command, "Coming of the Fuzors" Parts 1 & 2): “Optimus, how did ya do it?”.

In the original English version of the show, Rattrap speaks with a Brooklyn accent.

In the episode "Code of Hero" Rattrap is seen in his original state during Dinobot's funeral, even though he had already become a transmetal, most likely a goof on the show's animators.

The show bible for Beast Wars describes Rattrap as a wise guy who is inspired by Bud Abbott. He is described as being a five foot long rat. His gun is called a fusion rifle. He has infrared-vision and enjoys jazz music.

The television series depicts transmetal Rattrap as having his backpack in robot mode rotating 180 degrees so that his rear wheels are at his shoulder level, but the toy does not do this, leaving his rear wheels alongside his hips. The show also depicts the wheels as removable, so they can be used as shields, but on the toy they cannot be removed.

Rattrap was one of only three characters (along with Cheetor and Waspinator) to survive from the beginning of Beast Wars to the end of Beast Machines (Although Optimus Primal, Megatron, Tarantulas and Rhinox returned to life in the comic storylines after Beast Machines).

Animated series

Beast Wars season one

Rattrap was the navigator of the crew of the Maximal exploration ship called the Axalon commanded by Optimus Primal. He worked alongside Cheetor and Rhinox. The Axalon chased the Predacon criminal Megatron and his band of Predacons on their ship the Darksyde through transwarp space after the theft of the Golden Disk artifact. The Maximals and Predacons crashed on prehistoric Earth, where high energon levels threatened to destroy the crew unless they adopted organic alternate modes. Rattrap was given the form of a rat. At this point Rattrap had not developed his later loyalty, flatly disobeying Optimus Primal at several points if it contradicted his survival instincts, and openly criticizing him for accepting Dinobot into the group. Despite this, Rattrap would soon prove there was more to him than wisecracks and constant complaints: when Cheetor was captured by the sadistic Tarantulas, Rattrap personally tracked down and rescued him, battling and defeating the spider Predacon. This led to a short-lived rivalry between the two, and they clashed on several occasions afterwards.

When it appeared that Optimus Primal was killed by an alien probe in "Chain of Command", Dinobot attempted to seize command of the Maximals, but Rattrap was appointed second in command by Primal, when he contacted the Maximals from inside the probe. Although he led the Maximals in freeing Optimus he informed Optimus that he did not wish to command again. Indeed, ever afterward, he is seen deferring to Rhinox.

Eventually Rattrap developed an intense loyalty to Primal (despite his numerous complaints) and accompanied him on many missions. He was instrumental in sabotaging Terrorsaur's floating mountain of energon, and his spying experience came in handy when he temporarily "defected" to the Predacons in order to find out how the Predacons were bugging the Maximal communications. His small size and infiltration talents were also displayed when the Maximal defense computer Sentinel went haywire. Despite the numerous traps and defenses the malfunctioning computer threw at him, Rattrap was able to make his way to the computer core and shut it down. The other Maximals were convinced Rattrap was destroyed in the process, until the somber moment was broken by Rattrap himself. He was also nearly killed by Dinobot's Predacon created clone (Note: this was the only episode where Rattrap referred to Dinobot by his name). Rattrap accompanied Primal to free Airazor from the Vok ship, and was also present as Optimus flew a modified stasis pod to destroy the Vok planet killer - only to watch helplessly as Primal was destroyed by Megatron's treachery.[2]

Beast Wars season two

At the beginning of season two, Rattrap was reformatted into a transmetal rat with the additional mechanical attributes of a dragster (wheels and an engine) by the quantum surge that was created from the explosion which destroyed Optimus Primal. Following the (temporary) death of Optimus Primal, Rhinox took the initiative, leading the remaining Maximals in defending the base from overwhelming Predacon forces. In the fight, Rattrap became the first Maximal to face the newly transmetal Megatron in a brief one on one showdown. Though no match for Megatron's raw might, he still managed to score a rather embarrassing hit against the giant by taking out his legs when Megatron charged at him. However, Rattrap was accidentally taken out by an out-of-control Cheetor, and the two would have been killed if not for the intervention of Rhinox.

For most of the second season (having cowed Dinobot into submission beforehand) Rattrap found himself in the position he disliked most – being left in command. With no other options he led Cheetor and Dinobot in a stand against the Predacons to buy time for Rhinox to succeed in finding Optimus. Although they fought valiantly (even sparing Silverbolt as a tribute to Primal) the Predacon numbers and firepower proved too much. All three would have been killed, but Optimus returned as a transmetal and single-handedly fought off the entire Predacon force. Later, Rattrap would be forced into a peace-maker role of sorts again. When Megatron used the Golden Disc to take control of a Vok ship that abducted Airazor and Tigatron, using it to capture Primal, Rattrap was the one who convinced the other Maximals of the necessity of an alliance with Tarantulas to stop Megatron taking the ship back to Cybertron. Rattrap infiltrated the ship and freed Primal, leaving him to battle with Megatron as Tarantulas took out the ship's power systems.

Rattrap's friendship with Dinobot would be sorely tested when the warrior Transformer returned briefly to the Predacon fold. Captured by the Predacons, Megatron ordered Dinobot to kill the helpless Maximal but Dinobot refused and turned on the Predacons once again. Although Rattrap would make the decision to accept Dinobot back into the fold, after this Rattrap never fully trusted Dinobot again. However, events would be taken out of his hands. After an argument with Rattrap Dinobot set out to redeem himself in the eyes of his friends – and died doing so. Single-handedly driving off a full-scale Predacon attempt to wipe out the early humans, Rattrap and the other Maximals arrived just in time to hear Dinobot's last words. Tellingly, Rattrap was the first to salute the fallen warrior's spark as it joined the Matrix.

When Ravage arrived from Cybertron to capture Megatron, Rattrap took part in the daring assault on the Predacon ship, capturing Megatron. However, on viewing a recording made by the original Megatron Ravage switched sides and attacked the Axalon in his ship. Rattrap launched a solo assault on the ship, destroying it (and Ravage) with a few well planted bombs. Megatron's plan to alter history was then revealed and Rattrap and the other Maximals journeyed to The Ark to stop him. Taking out the Autobot defense gun with a well placed blast, Rattrap was nonetheless too late to stop Megatron from shooting Optimus Prime in the head and causing a timestorm that threatened to rewrite all of history.

In the second-season episode Transmutate, Rattrap makes an off-hand remark about his "great-aunt Arcee". This is an in-joke to Susan Blu, who was not only voice director on Beast Wars, but the voice of Arcee in the original Transformers cartoon series and Transmutate in that episode.

Beast Wars season three

Prime's life was saved by the unexpected side-switching of Blackarachnia, who helped the Maximals repair the damage to Prime's body. However, Megatron was able to destroy the Maximal base, and the Maximals were forced to move into the Ark to defend it from Predacon attack. To help defend it Rattrap was sent in a submersible, as he was the only one small enough to fit, (which he sorely resented, but actually quite enjoyed once in the water) to recover the defense computer Sentinel. The mission was far from smooth, as he was attacked by Rampage, and was only saved by Depth Charge. Once on land Rattrap and Silverbolt were ambushed by the Predacons, recovering Sentinel through teamwork – until a mid-air collision with Depth Charge (who had reluctantly come to assist) made them lose it, much to Rattrap's fury.

Rattrap would subsequently regard Blackarachnia with suspicion for her Predacon origins (similarly to his suspicions about Dinobot). When she went missing during a battle Dinobot's clone, Rattrap refused to allow Silverbolt to go after her – until the noble Maximal brought up his friendship with the original Dinobot. Surprisingly, he was seen expressing regret at her death in the episode "Crossing the Rubicon" (although she returned as a Transmetal II). Rattrap was subsequently seen mostly assisting the other Maximals in battle and guarding the Ark. After Megatron was captured, Rattrap returned with the other surviving Maximals to Cybertron on board the Autobot shuttle Omega Delta.

Unaired Beast Wars episode

One episode entitled Dark Glass would highlight Rattrap and his friendship with Dinobot. Set during season three, Rattrap discovered a copy of the original Dinobot's personal datatracks (downloaded in Bad Spark). Deciding to attempt to use them to bring Dinobot back to life in the body of the clone Dinobot, Rattrap recruited Depth Charge to hunt down Dinobot. Although successful in finding the clone Dinobot and uploading the datatracks, Dinobot resisted being taken over by the new personality. Dinobot would have killed Rattrap and Depth Charge if it wasn't for the timely help of Rhinox. In the end, Rattrap would have to accept that the Dinobot he knew as his friend was gone. However, the episode never made it beyond the planning stage.

Beast Machines

Rattrap in Beast Machines

Rattrap would reappear in the follow-up series to Beast Wars: Beast Machines .

In Beast Machines, he was reformatted into a technorganic rat. This reformatting resulted in the loss of all of his weapons, making him almost useless in combat. He was also the last of the Maximals to learn how to transform, leaving him stuck in beast mode. These issues, as well as him being the smallest Maximal, made him depressed as he felt that he was a liability for the Maximals. However, the revelation of his technical and computer hacking abilities having been greatly enhanced by his new form eventually made him an indispensable member of the team in their mission to discover the reasons behind their lost memories and Megatron's takeover of a virtually abandoned Cybertron.

Eventually, Rattrap broke away from the mold of "useless member" and became Maximals' computer expert. His new body let him hack into any console on the planet Cybertron, using his tail as some sort of advanced interface. He was also responsible for numerous Maximal inventions; including the device eventually used to turn Jetstorm back into Silverbolt. He also invented grenades which created fast-growing plants and devices which could interfere with Vehicon sensors. Towards the end of the series, Rattrap began forming a romantic relationship with fellow Maximal Botanica, even dropping the shields of Megatron's fortress/body at one point to save her life.


In the Japanese manga, Rattrap/Rattle's beast mode was designed to resemble Pikachu or Hamtaro.

Dreamwave Productions

Rattrap would appear in the Dreamwave Productions' Transformers Summer Special. After Megatron's capture, Rattrap had a dream (implied to be a suppressed memory) in which he was under attack by Dinobot's clone while testing some digging equipment. His appeals to what was left of his former friend's personality proving ineffectual, he was astonished to be saved by Bonecrusher, Optimus Minor and Wolfang. Although Rattrap was happy to discover new Maximals, the three refused to go with him back to Maximal base.

Fun Publications

Prior to his reformatting into a rat on Earth, Rattrap was a similarly sized Maximal who transformed into a motorcycle. Rattrap's origins mirror his role as a Maximal in Beast Wars. He serves as the team's hacker and weapons controller on the Axalon. Under his targeting the former Decepticons Laserbeak and Buzzsaw meet their apparent end in outer space.[3]

Botanica, Rattrap and Nightscream appeared together in the story Wreckers: Finale Part 2 by the Transformers Collectors Club in 2007. During the invasion of Cybertron by the Quintessons they worked together and came across the Quintesson working with the Wreckers.

Rattrap welcomes Trailbreaker back to Cybertron

Although there was no new toy for Rattrap in the Transformers: Universe line which followed the story after Beast Machines, Rattrap did appear in the comic book series in the form of his Beast Machines Mega sized toy - now rendered correctly with legs. Shortly after the reformatting of Cybertron at the end of Beast Machines Rattrap was amongst those who welcomed back some of the heroes of The Great War (Roulette, Shadowstriker, Sideswipe, Sunstreaker and Trailbreaker) back to Cybertron. However he was left helpless when they, Silverbolt and Blackarachnia were abducted by Unicron. After this Optimus Primal was resurrected by Primus as a response, and Rattrap once again served under him, being saved from a corrupted Blackarachnia by a resurrected Depth Charge.

Rattrap also appeared in the BotCon 2004 voice actor play. When Rhinox's attempts to stop Unicron pulling victims from alternate realities resulted in two groups of dimensionally-displaced Autobots being marooned on frozen planetoids, Rattrap was sent alongside Waspinator and Silverbolt to help. They ended up battling Unicron's minions alongside a crew of timelost Autobots (Bumblebee, Cosmos and Tracks) and the two groups of Autobots they had been sent to help (both from the RiD universes), and, with Rhinox's help, sent them back to their own times and realities.

Rattletrap is then approached by Ratchet and Captain Fanzone, who had been accidentally transported to Cybertron via a Space Bridge. Captain Fanzone uses Rattletrap's fear of organic life to discover where Shockwave is headed and also to gain another pass to the same restricted area, this one however was fake. Ratchet asked Fanzone how he knew about Rattletrap selling false documents, to which Fanzone replied "Eh, there's one in every town."
