Prism
Moving on, we have Prism, a mutant with the ability to refract light. While his powers might sound quite unique, they are not particularly useful in combat situations, and he ends up being more of a background character than anything else.

This character can deflect any light energy thrown at him without any problem, but he shatters in a thousand pieces when someone pushes or punches him. Although he is constantly getting cloned, he always ends up defeated.
