Powers and Abilities
Besides transforming into a musclecar and a motorcycle, Decimus Prime is able to alter his arms to create weapons, such as guns or swords. He also has enhanced speed on his alt-modes, enhanced strength on his robot mode and enhanced durability on all of his three forms. He can also create guns when in his alt-modes.
Decimus Prime can be affected by Dark Energon, becoming a mindless zombie until he reverts back to Ben.
If he is badly affected by an electrical charge while on his alt-modes, he is unable to turn back to his robot mode.
Due to his size, he cannot enter in small spaces.
