 This is most likely because of the legal issues surrounding the Tony Twist character, since Tremor's role in the book is to chase after Twist.Todd McFarlane has also stated in the past that he feels the character is very "cartoony" and thus not suited for current storylines.Tremor made a cameo as a new member of the Image comics team, The Brigade, and more information on this part of his usage in comics is being investigated.
