The Mysterious Stranger

The Mysterious Stranger is, as the name replies, a mysterious stranger. He appears to be a very capable gunfighter.

History
Next to nothing is known about this person. He is first encountered in Eastwood carrying a box and trying to keep his face obscured with his hat for unknown reasons. His hat is suddenly blown off his head by a gust of wind, but it is retrieved and returned to him by Twig, who says "Now you owe me!" in a sing-song fashion.

The stranger repays his supposed debt to Twig by slaying a radroach that's about to attack Twig and Scarlet, shortly before the destruction of Eastwood. After the radroach is killed, the stranger smirks at Twig and says the words "Now we're even" before suddenly (and mysteriously) disappearing.
