Luke - Street Fighter 6
Luke Sullivan appears as Street Fighter V's final character in Season 5 DLC. He is an American mixed martial artist(MMA). To honor his father's memory, Guile suggests he take his own path instead, resulting in Luke leaving the army and becoming a competitive fighter.
Having a military background gives Luke a variety of options, and he emphasizes getting close to his opponents during his attack style in Street Fighter 6. The flash knuckle is Luke's key tool, which he uses to extend his reach and change his trajectory in the air.
