Ultra Street Fighter IV had an interesting combo system, and there is still room for exploration within it; this video shows that there are still things to be learned–and Oni is an amazing example.
This video shows a slew of Oni combos, connecting off of meaty moves hitting at the last frame. While a lot of these combos are short and low damage, they are technically impressive–showing off a high degree of execution. One of the final combos is Deejay-specific, working only on him due to his enlarged hitbox.
