Concept

Jamie was created in response to the lack of Drunken Fist users in the Street Fighter series. Because he is also young, Takayuki Nakayama wanted to add current culture to him & thus made Jamie a breakdancer & set him up to be Luke's rival.The drink in Jamie's jug is called Yakutou which is more like a medicinal tea not actually alcohol. it's a special drink.

His default outfit is a modern kung-fu outfit, consisting of a yellow top designed like a hoodie with red drawstrings & white trims, matching yellow pants, a brown rope belt & grey sneakers with white soles. He carries a small black gourd with a red rope tie on the belt.
