For Fire.Freak. :D She wanted to know what Zack looked like in high school.

Originally, he just was going to have brown hair... but then my little sister, who technically created Zack (he was her character in the Rock Band video game), said I should give him blonde highlights. So I attempted that. xD It was hard to do on MS paint, just because it's paint.
Oh yeah, she also told me to give him pimples and a "beard". xD So that was on her behalf...

So yeah. This is pretty sloppy, but it was fun anyways. :)

Drawn on MS paint with a tablet.
Dedicated to Fire.Freak for requesting this.

Edit: Cleaned up the line art a bit. :d Also changed the skin tone a little.
