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 both armour and flesh, 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, Avis and Glaeba being killed. They soon got up and fled. The other three went their own way and Acerbus eventually found himself in the final confrontation of the Olympian War on New Vestroia. He eventually join Artemis, Latro and Gelus in fighting Typhon but was defeated. When Omega Robotallion confronted Typhon he chose to assist him alongside many other Bakugan. After the war he bonded with Kodo and his Bakugan and joned them. This improved his attitude and he became considerably kinder.
