Quote from LugioDon't worry, Bloo, I'm sure you will be fine, some examples that might help you:
Most Wanted: 1 and 2. As you can see, you don't need to hit the enemies 20x times, but you guys need to do some fighting, counter attacks and don't kill an enemie with a single punch, ok? Don't need to do a super-awesome animation, It's simple.
Rebellion made a giant marauder, for example. As you can see, you can include some ideas too.
Infinity Strikers made a really awesome animation, with cinematics, angles etc. It can be waaay more simple.
Outsiders: 1; 2; 3. Good examples too, good animation, not too short, not too long.
I see now, 1 has a club and No one hit K.O.'s. got it
