Galactus is Franklin's herald, so... /thread.
Bad news everyone...
Hmm, I'm not sure he can top Franklin (who I think is riddiculously overpowered anyway), but I guess Elixier oughta be on that list. He's still learning and can already recreate, create and decompose on a molecular level. Other than that, Quire was shown to be a Phoenix host in one alternative future at least and already has Omega potential as a telepath I guess. Then there's Wiccan *if* he can ever tap into the same power like his mom did again, there we go with the reality and universe-shaping again. Also as alrady mentioned Hope as a mimick, just copy everyone else. Oo
It's gotta' be baby Jesus. C'mon, it's Christmas.
Franklin Richards, but don't forget about Benny Beckley.
Franklin, but in terms of costumed heroes, Wiccan and then maybe Skarr.
Memphisto was scared of Franklin as well.
I know she's not the most powerful, but Hazmat can make nuclear explosions. That's gotta count for something.
