My brother and I have established a decent 2v2 team, with him being Drake and I'll switch between Toro and Heihachi.
People tend to go after Drake (I guess because he doesn't do as well up close), and I use that time to peck at them from the outside until I have my level 2, then get a multi-kill
My favorite time with this setup was when I was being chased by Raiden, and I used Toro's teleport move and got in close to my partner. He used his level 1, and would have gotten me if my brother didn't quickly silence it with Drake's level 2. We laughed about it for a while.
Ah, good times.
