i know about the str thing but if you check it out a herald's basic function is to find a world for his master and whuup ass just in case ppl dont wanna get eaten. gladiator can breathe in space, and i believe he doesnt need food or eats rarely, one or the other. so he would be a perfect candidate, but i think that galactus might be afraid to further empower a being so powerful. cuz if some strange ass way SS always find a way to keep him at bay. so i could only imagine what an unstoppable force he would be cosmically enhanced.
besides its completely in the realm of possiblilty cuz he's so blindly loyal to the Shiar that if lilandra or Deathbird tells him to herald for galactus he'll do it
yea a herald is meant to be physically formidable...but unlike Gladiator, Surfer can reconstitute matter, Terrax can manipulate earth, etc...They have the power cosmic...even the Kree had the right idea when they made Ronin artificially cosmic powered...he uses his powers to such a diverse effect, even moreso than Surfer!...he is not as strong or durable as Gladiator, but the cosmic factor forces me place him above...u read Ronin's last fight tith the FF? such a crazy bastard....he teleported Four Freedoms tower to the moon!
