Next Door Soldier

About
The Next Door Soldier is a mysterious entity that suddenly appeared during the events of Infinity Tour.

Like some kind of force of nature, the Next Door Soldier arrives at Goon functions on his own will.

Next Door Soldier is thought to be a modified assassin, who was upgraded with a metallic arm and enhanced fire breathing. This idea was proposed after he spit flames at Helium Man, burning him to a crisp.
