Seeing the teaser intro for this episode as a kid I was thrilled to be getting an actual Hulk comic book villain.  Despite that I really didn't like the episode at the time.  I think I would have enjoyed it much more if it had been an origin story for The Leader.  Watching it again after all these years, I liked it a little better than I thought I would.  There seemed to be many other appealing directions to go with the Leader than involving him with a motorcycle gang, but I have to say that image of him with a motorcycle helmet on was almost worth it.  I was totally surprised when researching this site that Paul Dini wrote this episode.  Paul has written many great cartoons of the DC animated universe and I'd endorse anything the guy has written.  I assume that this episode would have to be one of the first things he had written and with that in consideration it's an okay episode.  It's a standard "villain with a powerful weapon" story and doesn't have much depth of characterization but still provides some genuine entertainment.  

      
I'm of two minds about this episode. On one hand, there is quite a strange plot involving a group of bikers attempting to steal a load of vibranium. On the other hand, there is a great dream sequence in Banner's mind at the beginning and the main bad guy is actually a bona fide Hulk comic book super-villain. The opening, with Banner running away from the Hulk in a dreamscape, is extremely effective at showcasing Banner's thoughts and fears regarding the Hulk. It's quite unnerving when Banner is finally caught in the giant Hulk's grip and is about to be pulverized just before he wakes up. Unfortunately, even for a cartoon, the Screaming Vultures come across as a pretty pathetic bunch of bikers. Even with their "super-powers", they are hopelessly outclassed by the Hulk. Fortunately, their credibility is somewhat increased when the Leader shows up as their boss. Fortunately, the Leader is taken faithfully from the original comics, and is instantly an intriguing character. With the substance vibranium also showing up in this episode, it's pretty obvious that writer Paul Dini was well versed with the original comic books. Even Banner makes his characteristic comments on what the Hulk may have done after each change. Since references like this were sorely missed in other episodes of the show, I'm especially pleased to see them, even if the sight of the Leader on a bike with an outsized rider's helmet is unintentionally hilarious!
