I've been thinking about this for a while. Because the Scout from Team Fortress 2 is one my favorite characters from any game, I've been thinking of converting different miniatures into the different characters from TF2.
Scout - Scout (obviously!

) I think I'd make the bat from a sprue and some green stuff. But I need to find a head with a baseball cap.
Heavy - Most likely a marine with a heavy bolter. I could use one of the stock bald-head marines, but the torso needs to have a bit of a belly. Maybe paint some Soviet symbols on him.
Sniper - Scout with sniper rifle. I'd need a cowboy hat, and some sunglasses.
Soldier - A Marine with a missile launcher. Maybe I could find a WWII miniature and use the head.
Medic- I guess I could use an apothecary, or use a Dark Angels robe and make it into a lab coat.
Pyro- (I'm not an
IG player so bare with me..) use the head from the
IG unit with the gas mask. Give him a flamer.
Engineer - A techmarine I suppose, with a hard hat and some overalls!
Demoman- Not sure who he should be
Spy - This is the toughest one, I don't know who he fits in closely with. I suppose a scout with camo cloak, but how do I give him the business suit look?
BONK!! ~ Scout's bat counts as a power weapon
Force-a-freakin-
naycha ~ Scout has fleet rule
How would you make a TF2 army?
