Re: LEAST favorite villain
Orca hands down. WTF was that all about? singlehandedly made me disown Larry Hama as a favorite creator of mine. From the more now commonly used villains it's Tommy Elliot. He is just such an irrelevant character due to being extremely unnecessary.
Though I credit Dini for making him readable cause I proudly still own that Heart of Hush portion of Dini's 'tec run and the Streets of Gotham series to this day. However the themes explored with him make much more sense being explored with other established Batman rivals or adversaries.
