1. Black Hand
I just thought that maybe he could stop the other player from dying, fire a black beam and raise dead goons to help you against other enemies
2. Jason Todd
as red hood with guns and able to use robin costumes, maybe he is a combination of hush and night wing.
3. Beast Boy
the player can decide what he changes into form a wheel of choice.
4. Green Arrow
fires into certain Lego walls to turn them into water ,he can fly, shoot fire and enemies he can also turn enemy weapons into gas.
6. Cyborg Superman
just the same as superman but has magnetic.
A big character with strength laser vision and invincibility.
