there called sniper ninjas and they fire sling shot ammo
If you look closely at the faces (more specifically the eyebrows) of all four ninjas, and then that of the green ninja, you will see that one of their faces match up exactly with the green ninja. That ninja would be Kai, Ninja of Fire. This is also supported by the fact that Kai is the only ninja that has used a new technique with his golden weapon; thus being farther along in training than the other ninjas.
depends on what you want to do with the group, how about green ninjas?
Green Lantern's weapon is the Power Ring.It was given to him by the Guardians . It can create matter and objects out of green energy . It is recharged by putting it into the Green Lantern Power core.
Since lord garmadon changed them into the mega weapon the ninja may have to defeat him and get them back
