Cliffjumper

Cliffjumper is one of the initial members of The Unit fighting the Decepticons on Volantis.

Journey to the Core
Cliffjumper and Ultra Magnus' Wreckers escorted Optimus Prime, Bumblebee and Jetfire to the Well of AllSparks when they made their journey to purge Cybertron's core of Dark Energon.

Saving Arcee
During the Great War, Bumblebee, Cliffjumper and Sideswipe broke into Airachnid's lair to arrest her and rescue Arcee and her partner, Tailgate. However, they were only able to save Arcee because Airachnid had already killed Bluestreak.

Sea of Rust
After the repelling the Decepticon attack on the Ark, Optimus Prime sent a search team composed of Jazz, Sideswipe and Cliffjumper to look for the Lightning Strike Coalition who went missing in the Sea of Rust. Jazz and Cliffjumper were forced to split up and take seperate routes, but thankfully Cliff had the experimental cloaking technology and used it to sneak through the various Decepticon patrols and defenses.

Jazz and Cliffjumper eventually meet up and found a crevasse in which the Lightning Strike Coalition force went missing. Cliffjumper initally wanted to go, but Jazz went instead, much to his annoyance. However Cliff was much more happier up top as Jazz found the dead body of Sludge, and his killers, the Insecticons who attacked him in swarms. Jazz was able to escape and the two made a bolt for it. However they then came across a lake of pure Energon and a tower projecting immense power. After sneaking through more enemy patrols, they discovered Shockwave talking to Starscream about the tower. However as impatient as Cliffjumper was, he tried to jump Shockwave, only to be caught and forced to engage him. But a swarm of Insecticons soon attacked as Shockwave retreated. Cliffjumper then found himself trapped in the control room of the tower as Jazz was forced to fight the Insecticons. However Cliffjumper was able to sabotage the tower and free himself. As the tower went critical, the two Autobots were able to escape thanks to Sideswipe and reported their Energon findings to Optimus Prime.

Final Exodus
After Metroplex sacrificed his life to power the Ark, Cliffjumper was seen ordering all Autobots onto the Ark.
