This was requested by who wanted me to draw his OC Alex. Since I planned on drawing him along with his best friend Billy, I decided to do this. Here are the boys together like Mario and Luigi in this artwork for Super Mario Advance: https://mario.wiki.gallery/images/2/23/Mario_Bros_Super_Mario_Advance.jpg which seeing them together makes me think of Sonic and Tails since Alex is blue and has the former's shoes and Billy's orange with the latter's shoes.
