The Hero with Cancer

Endeavor vs ???

"Hmmm..oh! Here's one now!" The thing said as it spotted Endeavor. "This will be FUN" he said as he lunged in his direction.

Endeavor quickly dodged, and blasted it w/ his powers. "So your the thug whose been killing all those people. Well let me tell you...THAT STOPS HERE!!" He screamed as he sent a massive fireball towards the monster. The monster dodged but was caught by a burning fist to the face, sending it back by about 13 inches. "I figured you'd be smart and try to run, but I guess your as dumb as all the other villains!" He exclaimed while cocking his fist for another attack. But as he threw his fist, the monster caught his arm and executed an arm drag. The moment Endeavor's back made contact with the floor, the monster dropped it's fist on his face. Afterwards, it jumped back and waited for him to get up.

"Nice try hothead, but that won't work on me twice! My quirk is Adaption and Evolution. I can adapt to any given situation I'm in, and my body will evolve based on said situation."

Then, Endeavor managed to get behind it, and landed a blow right on the back of the head stunning it. Then he kicked it's back sending it forward. "Never monologue in front of your opponent, ROOKIE MISTAKE!!" He screamed while launching multiple fire blasts in its direction. Since the blasts were everywhere, the monster had no choice but to take the hit. But to his surprise, the monster was barely affected by the attack.

"Fool, I have evolved to be resistant to heat. You've already lost." It said while it lunged at him landing two blows to the face and one more to the gut. "Die" it said as it jumped 8 ft into the air, setting up for an aerial attack. But it was blasted out of the sky.

"You may be fire resistant, but that doesn't mean you still can't get hurt by my quirk! Not to mention, you keep leaving yourself open!" He said as he proceeded to attack it, launching fireballs left and right while using his legs to kick him low. The monster fell down and was almost about to get his face smashed into the pavement. It quickly dodged and regained its stance. Then they clashed once more, both exchanging blows. Fireballs were going everywhere. However, the monster had the advantage as it kept hitting the vital spots of the human body based off its knowledge of human biology. Not to mention its newfound fire resistance. It wasn't long before Endeavor collapsed.

"D-damn it!" The hero said while gritting his teeth. Blood was trickling out of his mouth.

"Sorry hero, looks like your going to DIE!!!" It screamed while launching its supposedly last attack.

But to his surprise, he still had enough energy to dodge. 'Damn, at this rate, I can't stop him! At this rate...' "N-n-NO!! Your not getting away with this! As long as I'm still standing, I, Endeavor will fight! As long as I still have the strength, I will get rid of the garbage of this world; VILLAINS LIKE YOU!!! IF I HAVE TO DIE, SO BE IT!!" He screamed. Then his body started burning hotter and brighter. The flames on his body started growing bigger. "EAT THIS YOU PIECE OF TRASH!! SOLAR BURN!!!" He shouted. "RAAAAAAAAA!" Then his body exploded into a giant supernova (like when Vegeta exploded to try and kill Majiin Buu). After the explosion, everything in the area was burnt to a crisp. At the center of all the carnage lied a gigantic crater, where Endeavor was lying unconscious. His body was in a critical state.

Unfortunately, the monster survived. "D-damn! I didn't expect that. I'd loved to finish him off, but the heroes are close by, and that blast took a number on me. Damn you Endeavor!" The monster exclaimed bitterly. After which, he retreated, barely escaping the other heroes.

Once the heroes arrived, they called the nearest hospital and did their best to keep Endeavor alive.
