Metamorpho and Ms. Marvel

I remember being very happy when the Justice League cartoon first hit the airwaves.  I was thrilled that my favorite comic team was finally getting the animated treatment that they always deserved, and I didn't think it could get any better - and then I found out that Metamorpho was going to be a guest star in the first season, in a two-part episode no less!  Metamorphosis remains a highlight of the series for me.
