Chaos Attack Robo-Dexter 3000

Dexter is one of the playable characters in Cartoon Network: Crossover Chaos!!. He wears his Dexo-Transformer in battle which makes him considerably larger.


A gifted genius from birth, Dexter spearheads many crucial experiments and creates his inventions in the seclusion of his secret laboratory, at least it was secret until Dee Dee managed to find it and create chaos in the lab on a daily basis. One day on a routine run on his experimental dimensional scanner, his alarms blared. Several rips in time and space were forming not just in his dimension, but others as well! Dexter went pale, knowing fully well the consequences if this went unchecked! Consulting with various scientific minds from across the multiverse, Dexter realised that the source of these anomalies would eventually unravel reality itself, ending all of existence! With no time to lose, Dexter got his best gear out for the job, but soon realised that this was not a battle that he alone should fight.


Name Info
Special 1
Ray Beam
Dexter fires a huge beam of energy from the right palm of the Dexo-Transformer. The beam is rather small when it isn't charged up and won't do much damage. However Dexter can charge it up for a greater effect, it having a longer range, being much thicker and as a result also deals much more damage.
Special 2
Somersault Blast
Dexter preforms a forward somersault, being blast away with the rocket boots of the Dexo-Transformer. When he lifts off it creates a blast which deals damage. When he lands the ground will crack. If performed well enough the Dexo-Transformer lands close enough to an opponent to latch onto. If that is the case Dexter does a backwards somersault blasting the opponent away. This does more damage than the first somersault.
Special 3
TNT Throw
When Dexter gets hit he grabs the opponent then shoots a TNT package against the opponent which sticks to them. Dexter then throws the opponent away and they will explode while they are in mid-air.
Chaos Attack
Robo-Dexter 2000
Dexter enters his mecha-suit the Robo-Dexter 2000. He fires his two fists at the opponent and gets them in a tight grip. He and the first then fly into space where Robo-Dexter releases the opponent which is immediately followed by a powerful laser beam from Robo-Dexter's eyes.
