What are some other grapplekinos besides Bionic Commando, Magical Quest, Umihara Kawase, Super Castlevania IV and Bloodlines?

Absolutely. It's early 90s Capcom.
The first one is the most challenging one (not super hard but enough for it to be a fun romp), while 2 and 3 are easier, but great co-op games as well.
Fantastic games, from a distant era Disney comisioned video games to one of the best game developers in the world at the time.
