The Emotional Entities Vs Heralds Of Galactus

Ophidian, Predator, and Ion

Vs

Surfer, Morg, Terrax, Stardust, and Firelord

Do the hostless entities have actual fight feats?

They could....possess the heralds , I guess.

Don't the EE's like NEED a host of some kind in order to function?

yes. even krona stuffed the entities into hosts so he could use them.
