Gregor was hurt, but he was trying to control the spread of the flames, while protecting Faultline and Shamrock.
Faultline seems to be the one in most trouble against Burnscar, power-wise. I mean, look at this:
- Newter can easily dodge most of the fire, but suffers from having a touch range offensive ability against a ranged enemy.
- While he’s not dextrous, Gregor’s slime can be used to put out the fire or stop the fireballs in mid-air, and probably has the best shot at actually hitting Burnscar with anything useful. He’s also a tank, able to take some hits for the team.
- Shamrock is lucky, which ought to help in a lot of ways, at least as far as dodging goes.
- Spitfire has a fire-resistant costume, though she’s also Burnscar’s main target (by the looks of it) and Burnscar is immune to her offensive ability.
Faultline, however… she can cut through things. But cutting through fire doesn’t help, and the enemy can teleport so blocking the path is more trouble than aid as long as there’s a fire on either side. Her costume doesn’t protect her from fire, nor does her biology. Everyone else has defensive advantages, but besides basic armor, she doesn’t have defensive or offensive features that are particularly useful in this fight.
His skin glistened, which made Elle think he was covering himself in something that would protect him from being burned.
That on top of what I just mentioned? Gregor is definitely the MVP here as far as powers go.
