Cliffjumper is the name of several fictional characters from the Transformers franchise. His name is usually associated with an Autobot whose toys are often red repaints or remold of Bumblebee toys.
Transformers: Generation 1
Cliffjumper's bio indicates that he compensates for his small size by being the first to rush into any dangerous situation, desiring only to beat up "Decepti-creeps." Although this trait has his fellow Autobots' respect, occasionally it ensnares him into situations he cannot handle. His motto is "Let me at 'em!"
Cliffjumper's weapon is his glass gas gun, which fires a gas that turns metal as brittle as glass for a short time. In the episode "Fire In the Sky," he mentions his gun has a "defrost cycle" to melt ice.
According to original tech spec notes written by Bob Budiansky found at Iacon One in 2006 the original name for Cliffjumper was Blow-Out, a name later used for a Generation 2 Autobot.
Hasbro registered the name Cliffjumper for U.S. Trademark in October 2003.
Animated series
In The Transformers animated series, Cliffjumper was part of the original Autobot crew of the Ark. When the Autobots and Decepticons were reawakened, Cliffjumper was given the alternate mode of an Earth car. He and Hound were sent to scout out the location of the Decepticons. Although ordered not to engage the Decepticons, Cliffjumper took the opportunity to try to shoot Megatron, revealing their existence to the Decepticons. Because of this, Hound was blown off the road by Laserbeak – something that made Cliffjumper regret his impulsiveness. Hound, however, did not blame him, quipping that he was only sorry he missed.
Cliffjumper's bravery was often a boon to the Autobots – as well as a problem. In the episode "Changing Gears", Cliffjumper's rash actions helped the Autobots get past a Decepticon force field and stop their Solar Needle device from destroying the sun. However, Cliffjumper survived the blast but he ended up having a temporary concussion which he was able to recover quickly.
In the episode "Traitor", Cliffjumper overeacted & developed a belief that Mirage had sold them out to the Decepticons after missing a Decepticon power plant while on patrol. Cliffjumper followed Mirage, who was devising a scheme to prove he was not a traitor by setting the Decepticons and Insecticons, who were in a feud, against each other. However, Cliffjumper misinterpreted his actions. Reporting back to base, Cliffjumper told Optimus Prime what he saw and then believed he must be stopped but Prime decided to go back to the power plant to stop the Decepticons then find Mirage so they can hear his side of the story with Ratchet accompanying them. Once they got to the power plant, Cliffjumper, Optimus Prime and Ratchet saw no one there until Mirage, who's been implanted by one of Bombshell's cerebro-shells, shows up as he explains to them that he was setting up the two factions of Decepticons against each other. However, Cliffjumper doesn't believe Mirage's story. Being led into an ambush by the Decepticons and Insecticons, Cliffjumper knocks Mirage unconscious. Listening in on what Optimus Prime and Ratchet, who removed the cerebro-shell that was controlling Mirage, were saying when they sum as to why Mirage set them up, Cliffjumper realizes that Mirage didn't betray the Autobots, was telling him the truth about setting up the Decepticons as well as not seeing them while he was on patrol. Cliffjumper finish the battle, but retreated when Megatron destroyed his own power plant. After returning to base, Cliffjumper apologized to Mirage for not believing him and making him go through so much trouble.
In "Starscream's Brigade", Cliffjumper and Jazz were invited as guest of honor for an unveiling of a statue for their leader Prime but were under attack when Starscream showed up, after he broke off from Megatron, along with his newly created Combaticons. During the scuffle, Cliffjumper suggested to Jazz into calling headquarters for help but were captured before they can make the call, as Starscream wanted their Energy absorber for the Combaticons. Cliffjumper with Jazz were chained up at a water and power plant but they did get rescued by the other Autobots when they found their location.
