As someone who loved the animated movie, Cobra La, Serpentor, and all that schtick... I'd like to throw a vote out to Big Lob as well.
He practically ruined that movie for me. My wife walked in on me watching the movie the other night when the obstacle course scene was on and Big S-O-B is narrating himself. I felt like a jackass.
The only good thing I can say for it is that it made Serpentor yelling Cobra-La-La-La-La-La tolerable by comparison. I almost laugh at that part, but then I think, at least he's not saying "Serpentor makes his move... Serpentor breaks right, flanking Duke... he throws his snake into Duke's heart.... SCORES!!!!"
My blood pressure is being raised just typing this.
