Aoi Kurenai
Mad Skillz
Blade's. I think Blade actually has the best ending to any tokusatsu I've ever seen, it's a shame the rest of the show couldn't be that great, but it really is an ending that has always stuck with me. After that, Hibiki (despite it basically being a rip of that speech from episode 23(?) ) and Agito. Kuuga gets a special mention just because it was so incredibly unique. It's one of the few tokustasu products I've seen with no tokusatsu elements in it.
