As this series' equal to the Joker, Jack Spicer is generally depicted as an intelligent, psychotic, ambitious, and resourceful individual whose shortcomings ultimately lead to his downfall.

Sometimes, Jack Spicer can best be described as "cowardly". While his ingenuity, insanity and sheer intelligence can be a force to be reckoned with and his strength isn't to be underestimated, his cowardly and meek personality keeps him from achieving his goals.

His more pathetic qualities notwithstanding, Jack can be very dangerous and manipulative, and he is not to be underestimated. Over time, Jack Spicer became a monster, exhibiting psychopathic, sociopathic and manipulative behavior and also was highly intelligent, able to execute morally appalling plans and criminal schemes to get success, but most of his plans usually end up in defeat, mainly due to something or somebody ruining his plans. And that somebody was Danny himself, a rivalry was renewed in the most hatred inducing way.

An impression of Danny Cooksey would work perfectly.
