The opening to Gekiganger 3! The part that comes before or after this in the OVA (I forget) is already on YouTube, but this part isn't!
Hints to the uninitiated. Gekiganger 3 is a fictional anime that never existed, meant to represent cheesy 70's sentai anime. It exists only as an anime characters of the more recent 90's anime "Martian Successor Nadesico" watch. :)
