This is Joe
(Yes I used a picture because I was too lazy to describe how he looks....)
Though he's also got Hazel eyes and a little bit of stubble on his chin and upper lip)

He's about 19

He's chill, laid back, wary of strangers, go-with-the-flow, protective of friends, and all around easy going
But he's also got DID (dissociative Personality Disorder)

So meet Mack
He's kinda shy, skittish, and reclusive, but loves spending time with friends and can be clingy at times.

And George
He's gruff and grumpy, keeps to himself, frowns a lot, and trusts few.

Joe and Mack are good friends of Garrett (a Hetalia OC)
They met while running from the cops cause they were stealing from a store one day.
Though George isn't so friendly....

Joe/Mack/George lives in various places in Ontario, mostly in abandoned houses and such.

You can tell, if you know him well enough, who is who by the color of his eyes. Though born with Hazel eyes they turn blueish for Joe, brownish for Mack, and greenish for George.

Usually Joe is in control though sometimes Mack is, George isn't so often.

Though they don't switch all the time and sometimes can switch intentionally, but that's mostly Joe who can.
