Jax is a Remedy

Ruby Summers (Peter David & Valentine De Landro)

From Marvel Universe Earth-1191 (which is also the same reality Bishop is from.)
She is the Daughter of Scott Summers (Cyclops) & Emma Frost.

Powers are:

• Optic Blasts: Similar to her father’s, but is black and take 93 seconds to regenerate
• Invunerable Ruby Form: Capable of turning her skin into a ruby form similar to her mother’s, this form can be maintained indefinitely, and prevents visible aging. In this form, she can survive without sustenance.

I hope we do see more of Ruby Summers maybe in Earth-616 Universe.
