This should be the last one. I have some notes, though.

C,D: very very similar to the "I'm shooting" thingy on the Toy Biz Marvel Legends Warmachine. My Warmachine has all its pieces though.

H-J: Spider man something or other, obviously. I don't think I have a Spidy these go with.

L-Q: almost certainly G.I. Joe.
L looks like the sword for Jinx/Slice in the Valor Vs. Venom 2-pack.
M looks a lot like the sword for Storm Shadow in the G.I. Joe vs Cobra Storm Shadow/Snake Eyes 2-pack. But again, for both of these, my matching figures have all their gear.
O fits a G.I. Joe backpack hole. P and Q fit inside O. O also has holes for... something? in that horizontal piece.

R: looks like claws for X-23, but my X-23 has fixed claws.

T could be a shoulder pad/armor?

Y: this is the same piece that goes with the Toy Biz Marvel Legends Omega Red, but I have FIVE of them while Omega Red has fittings for 2. It's very flexible and stays in the shape you change it to. Is there another figure/toy that uses this same piece?
