Strongest Character Galactus Can Beat?

Unicron maybe?

at his strongest?

I'm guessing this current Big G so...

Adult Franklin Richards: I think they were about the same level before the Lifebringer transformation.

Lord Order and Lord Chaos: He did this fairly easily.

Some versions of the Phoenix Force

Fully powered Tyrant

These are the names that come to mind right now

yes

and didn't adult franklin make galactus his herald? lol

yes

@violencejack: No he ain't beating Unicron sorry, he is on a completly other level, but Galactus is no slouch, it is hard to say who he would beat be strained to beat.

@frisky: yes he is.Current is Lifebringer who curb-stomped 2 Regular Galactus level characters at the same time.

@hittheassasin: In his True Form Unicron dwarfs the weapon known as The True Star Saber which is capeable of destroying the entier TF multiverse which is described as infinite with a single swing, his power is beyond that.

Here is a scan of what his avatar can do by just moving.
