Ion Vs. Franklin Richards

Who wins this?
Most powerful DC hero! (except Spectre backed by God)
OR
Most Powerful Marvel hero!

Ion, but only b/c we have not seen what FR can really do yet

Rf is only celestial level at best and ur comparing him against IOn?

FR at full-potential=Celestial level

Ion is MUCH more powerful then that

Ion wins 10/10

I love ION but, I didn't know he was greater than a celestial!
Question: Can anyone please define a Celestial and their abilities/limits for me please?
