Alto Scarab is a Pyrus Bakugan that is partnered with Kodo and was the evolution of Scarab. During the events of the Olympian War his body was badly damaged and Spera sacrificed herself to restore him to health, thus making him evolve and changing his genetic code. Making him part Delta Kodokor, part Phantom Dharak. Oddly though, he didn't gain any of her Haos abilities or characteristics.
His personality hasn't changed much from his previous form but he seems less violent but appears to have more of an ego, thinking that he is the ultimate Bakugan and that no one can take him down. He is as merciless as ever and crushes his opponent without any hesitation. He seems to show more respect towards his teammates and allies and even encourages them to try their very best. Scarab is extremely intelligent but fails to put this into battle, favouring brute force over strategy. He still has a great respect for Spera and likely won't ever truly get over her death.
