Yes, he - and I do mean HE - looks like FFX/X-2's Lulu and there's an easy explanation to it: Mihail - thy character presented - is Lulu and Wakka's second son in a AlternativeUniverse me and my friend 'created' afrter she first talked me into it...
Mihail has a twin sister tho' they don't really look that much alike.
He was the sickly one from the begining and Dawn has always settled the scores with bullies instead of him, yay.
Much happened and we get to the reason why he has a burn scar - yes, it's suppose to be a burn scar the first ever I've drawn ^^' ...
*Drum clatter* A fire blast gone wrong!!!!!
Now there you got it, no further questions?

p.s. I probably move this one into scraps if I ever get the line-art coloured with photoshop since I'm not that pleased with my half-assed looking colouring....
