Maybe the least heralded (Marvel jokes!) of all of the ’90s Marvel animated series was this short-lived blend of 2D and computer animation.
The ’60s Thor shorts from The Marvel Super Heroes began with this brief intro that sounds like something out of a Broadway musical.
In recent years, most Marvel TV series have done away with these sorts of elaborate intros, opting instead for brief title cards.
Sadly, the opening to Spider-Man: The New Animated Series, an otherwise fun show loosely inspired by the Sam Raimi Spider-Man movies, features a fairly unimpressive theme song.
