Extra life sonic 

Extra Life is a form of Sonic from Sonic the Comic who was trapped in a monitor, and then got Tails to get him out so that he could unleash destruction. In this mod, it appears that he somehow got Boyfriend to get him out of the monitor, and he burnt the background, until later in the song he gets put back into said monitor, like in the original comic.

Appearance

Extra Life looks like the original Sonic, but with a few differences. His quills have turned into faded blue, his skin is now more tan, and he has noticeable canine teeth. Past that, he still has the red power sneakers with white cuffs, tan arms and mouth, 3 quills on his head and 2 on his body, 2 eyes put into one, and gloves with cuffs.
Inside of the box, the monitor has a white background with his head inside with no mouth. The monitor itself has a square silver frame and an upside down T stand, and multiple dark gray buttons next to a red one.
