Acerbus is an Abyss Phosphos that is partnered with Kodo. His Mechtogan is Mars. He was once an evil Bakugan that served as a subordinate of Typhon. He eventually defected and joined Kodo and his team.
With seven ferocious heads in his Bakugan form, Acerbus spits deadly poisons that not only paralyses but also poisons and badly burns the opponent, eating away at their armor leaving them defensless and unable to block his bone crushing attacks. With sharp claws tipped with deadly poison the opponent slowly grows weaker as he circles his enemies, moving in for the kill. He has an extremely brutal fighting style, showing no restraint or mercy towards his opponent. He is usually very arrogant and refuses to lose in battle, doing almost anything to take down the enemy and leave them badly injured or even dead.
Acerbus was once cruel and merciless, caring for no one but himself and his own interests. He loved to watch his enemies suffer before taunting them and slowly striking them down. He also had a supposed great respect for Typhon and wanted to be just as powerful as him and to fight as equals. He was shocked when Typhon declared that he couldn't care less about what happened to him and that he was a mere servent in which to do his bidding. This enraged Phosphos and he angrily attacked him, only to be beaten down alongside Artemis, Gelus and Latro. They soon got up and fled. The other three went their own way and Acerbus eventually came across Kodo. Being hurt, he begged for help. Kodo and his team reluctently healed him and they bonded, resulting in Acerbus joining the team. Since then he has been happier and more respectful towards his opponents. He gets along well with his new teammates and is generally quite kind to them.
