It's worth checking if Snowcat has a moving little panel on it's back with a minicon peg on it
All three should have missiles.
Might be interested in Snowcat and Demolishor.....
Yes, Snowcat does have that moving panel with the peg on it. As far as I can see those three are complete. I'm astonished Demolishor has all four missiles. What the intention is for these I don't know yet, there are 19 assorted Armada/Energon figures. If they're unwanted and I can move them on I'll let you know, but as I don't have these particular three in my own collection I'd probably nab them myself!
Nothing wrong with asking for help in IDing TFs, because it's all around great fun for all of us. But if ever you can't, or can't wait for a responce, www.tfu.info has an amazing "id your bot" resource, that has every toy in their catalogue organized by color and alt mode. It only gets a little squirrelly when you have to search through red trucks, or yellow cars.
I think Towline, Inferno, and Mirage weathered the gimmick best. Downshift doesn't suffer from it, but I feel he's pretty neutral. Not terrible but not great. Hotshot did better than he's given credit for. Rodimus IMO fell completely flat.
