He was later made available in the Western Reactor.
Uncle Sam is based on the same figure that appeared on the poster "I Want You For U.S Army." Uncle Sam is an old yet muscular man with white hair and a goatee. He wears a white shirt with a long-tailed blue jacket imprinted with white stars, red and white striped pants, a top hat that matches his jacket, a shoulder guard with gold star, and red bowtie. He dual-wields two-barreled magnum guns and wears a belt with gun holster on his right side, which he stores his second magnum in. His right hand is blue with white stars, which fades away when it reaches his wrist.

I Want You to Die
When many thought that he was but a symbol of a long-gone past, he has returned, and is now ready to fight and defend the honour of an entire nation! More real than ever, he will teach his opponents the true meaning of his motto - "I want you to die!"
- The "I want you to die" second attack is a parody of his "I want you for U.S Army" poster.
- His Western Reactor version appears to be an old-west sheriff.
- The stats of both versions are approximately equal to a gold mutant.
