Marchionne

"To simply put it, you're a failure." - Marchionne to Mario
== Powers and Abilities ==
Marchionne has the potential to be an extremely powerful and deadly entity, if he so desired. As he has witch powers, he has a skill set even more vast than Mario.
Marchionne is much more physically impressive than a regular human being, possibly even more so due to the fact that he's a witch. Since he is Mario from a former life, it is reasonable to assume that he is just as physically capable as him.
Marchionne is capable of creating barriers to protect himself and others from outside forces or to prevent people from entering or leaving certain places.
Marchionne can create several manifestations of himself, mainly for combat purposes.
Marchionne has the typical ability that every witch possesses, and he's able to use telekinesis.
As a spirit, Marchionne is capable of possessing the living. He used this to inhabit Mario's body after Mario's soul was "Rescued" by Professor E. Gadd, effectively reviving Marchionne.
