In this piece Jim Rugg created for UDON's Street Fighter Tribute book (a book full of hundreds of illustrations of Street Fighter characters), a pop art-styled Ryu is beating down a shirtless Street Fighter character I don't recognize. While doing so, he's making that sound that's like: adoooeuukehh, addoouookehh! (Eh? Know what I mean?)
If you like this piece, chyeckkk out Rugg's other work, which includes comic books and zines and stuff. (Disclaimer: depending on the workspace's prudity scale, site possibly NSFW.) Have fun!
