Sersi vs. Jean Grey

Who can dish out more power longer?
Eternal or Omega level mutant?
no phoenix.

Sersi in a curb stomp imo

I forgot to say that this is only power output match. Which type of body is more powerful energy source since both are said to be unlimited source, eternal's or omega's.

I would think Eternals were created by the Celestials.

mutants were created indirectly by the Celestials with the Omega being the reason for the experiment, to create beings that will replace the abstracts.
