What you'll need-
1. A Super-man minifigure
2. A Star Wars clone trooper minifigure
3. A Hawk-eye minifigure
(BTW this is my first 'ible so tell me if it's good.)
Step 1: The Arms Pt.1
Get the clone troopers arms and take them off. then take out the hands. Remove Super-man's arms then replace them with the the clone troopers arms, ONLY THE ARMS AND NOT THE HANDS. It should look like the picture above.
Step 2: The Arms Pt.2
Get Super-man's hans and remove them from the arms insert the hands into the clone trooper arms on Super-man's body. It should look like the picture above.
Step 3: The Face and Everything Else
Remove his cape. then switch heads with Hawk-eye and put the head on the side where it shows goggles. It should look like this. Have Fun!
