Just finished watching it. Parts of the story made more sense without the cuts that were made to this episode during the reruns on UPN back in '98-'99:
Chameleon trapping Spider-Man in the chimney, then transforming himself into Spidey.
Chameleon taking out Shana while was on a mountaintop.
Chameleon via a speaker introducing six of the seven superheroes, and telling them that he'll get his revenge for them stopping his plans in the past.
Although like other episodes, UPN-run scenes were cut, but some of those are minimal. They need to get this show on DVD soon.
Hopefully, ToonDisney will air the other episode ABCFamily did not:
"Knights & Demons"
