Champion variants


The gemini will start of with both detacrhed; homever the smaller one will get enraged when the larger one is dead (Behaving as normal) it dosen't move as fast as normal one. There is also the possibility that only the smaller one is green.


Gemini starts off with increased health, but decreased speed witch is noticable if the larger one is colored blue. This makes Gemini much easier to beat but just longer. If just the small one is blue, he will move very slow. both twins overall health is increased.


Gemini starts with two smaller ones attached to the larger one. first one will deattach when large ones health is at half and second comes off when larger is slain. While the smaller ones are attached they will regenerate health and shot three-way shots.
