Dunno if this has already been talked about in this thread, but I found a way to infinitely stunlock Ustanak with Jake. Use the lock-on thrust punch on him, then as it ends, hit back on the stick and A to backflip away. As long as you keep the left trigger held, Jake will do the thrust punch again after the backflip, allowing you to repeat the process. A dodge in another direction can also work, but the backflip is quickest.
Also, Sherry can perform a second strike with her stun rod if you hold the right trigger after its normal attack, and it becomes very powerful if you hold it long enough.
