Uuhhh...whoever drew this, that is NOT the normal Squall...that is the Dissidia Squall which has both clothing & hair differences. Look up original pictures before you draw K.
Not normal Squall, that's Dissidia Squall over there pal & when was Laguna in ANY other game besides the orignal FF8?
Actually, what I think the artist is saying, is; the one on the right is "younger Squall and Laguna" and the left is later on. Because, what Laguna is wearing on the left, is the "daddy Laguna" outfit, when you meet him in the present. On the right is his young outfit. For Squall, the Dissidia outfit on the right is his 'younger' outfit. (Seeing as really, it's an updated outfit) and on the left is his Kingdom Hearts outfit, where he's older. Phew.
