Eon

He's indestructible, as far as we know. His physical body is atomically denser than what it appears to be: while proportionately 6'5", at rest he weighs just under a single metric ton.

Working on visuals.

Shield Creation
He has the ability to activate a spherical bubble shield around him that is impermeable from outside or within. He can change the size (and to much less variation, shape) of his shield at will at the expense of his health/energy. Eon is always at the center of his shield- if he moves while his shield is activated, the shield will follow him, pushing aside any outside matter. The larger his shield is, the heavier (denser) his body becomes.

Supernaturally Dense Tissue
Super duper tough body, heavy as hell. (Kinda tweaked this so it's not just a repeat of impenetrable shielding.)

Illuminate
Eon seems to show a no-hit and no-kill policy (even while being punched in the face), having been seen only as a part of the Illuminate's defensive muscle and refusing to participate in active combat. He acts as a mediator within the group.

Recent evidence suggests that he was coerced into joining the Illuminate.

"Put up your shield."

"What?!"

"Put up your goddamn shield!" She shoved him into the middle of the street, into the cacophony of screams and stumbling people searching for their loved ones.

"Wh... why?"

"Something bad's going to happen, I think I'm going to die!"

He yelled back, utterly confused. "What do you mean you 'think like you're gonna die'?! You're not going to die, stay put and look at me--!" She looked at him, blankly. He felt his blood chill.

"Just... stay under my shield, I can protect you- look!" He grabbed her by the arm and almost instantly raised his shield around them. Passerby bounced off the walls with dazed looks- this, unfortunately, wasn't the weirdest thing they'd seen that day. "I can protect this whole city, I think, just stay close to me-"

"Ian, no. Stay safe."

The last things he saw before the light hit him was a few shreds of newspaper, someone's tennis shoe flying away, and his fiance's apologetic eyes, her hair dancing as she gave him one last shove. His shield went up like a reflex and engulfed San Francisco Bay.

He woke up on a metal bed with air conditioning blasting in his face.
