Frenzy VS Colossus
"Frenzy is a mutant whose abilities grant her invulnerability, as she has steel-hard skin which is impenetrable by anything other than adamantium. She is resistant to any forms of temperature change, being able to withstand being frozen or engulfed in flames. A by-product of her mutant powers is superhuman strength, powerful enough to battle the likes of She-Hulk or Rogue (with Ms. Marvel's abilities)."
