Another G2 reference. Maybe you want to start a thread for G2 stuff?

Anyway, G2 Constructicon Hook, 80002/80001.

Got another mystery solved. #5831 is Pretenders Bugly!

Correction: you have Streetwise listed as 5854, but he's actually 5853.

G2 Windbreaker (80046/80045, 2626/2624)

I don't know if you want any G2 decals (since this is the "G1" forum), but I'll go ahead and share, just because I don't want my research time to go for naught.

First up is G2 Sideswipe (80012/80005)

Hi again. I have another "UNKNOWN" one for you.

This is Landfill (Autobot Targetmaster), #5977.

Just a small correction (I'm being nitpicky), but the reference number for "Attack Cruiser With Sprocket" is reversed and should read:
5725/5752

Identifying one of your "unknown" characters.

"Spinister" is #5806. You can cross-reference this with the scanned instruction manual on his profile page.
