Random Villain after committing a very evil act: hahaha, now what? What are you going to do with me!? I know you don't kill!
Billy is furious, there is smoke coming out of his ears and he is red with anger as he holds his fists and grinds his teeth
Marvel: I… I… I curse you! I CURSE YOU FOR YOUR SINS, YOUR HORRIBLE ACTIONS, I PLACE A CURSE ON YOU, IN YOUR BLOOD!!!
the sky closes, the environment begins to cool and the shadows around you seem to move, threatening to grow and swallow all the light
Marvel: THE DAYS, THE HOURS OF LIFE UNTIL YOUR LAST BREATH WILL BE FULL OF AGONY, YOU WILL SUFFER. WITH EVERY BREATH YOU TAKE, THE FEELING OF GUILT AND REGRET WILL BURN IN YOUR LUNGS, YOUR FACE AND YOUR TIPERS, I CURSE YOU TO A LIFE OF HICCUPING! --
Marvel: --A LIFE WITHOUT AIR. YOUR LUNGS WILL NEVER BE FULLY FULL AND NO SENTENCE OF YOURS WILL BE COMPLETE, EVEN IN YOUR SLEEP YOU WILL BE TORMENTED WITH THE MOST DISTURBING SOUNDS THAT YOUR OWN BODY WILL CREATE--
Villain: You dont mean-- *hiccup* --oh...
and then marvel leaves after handing the guy over to the police
the villain actually goes crazy some days later. he sobs incessantly. He can't sleep properly because he keeps waking up, the other prisoners don't stay close to him because he doesn't stop making those sounds, he choked several times because he was hiccuping while eating, his throat and lungs started to hurt because he didn't get any rest from the muscle spasms too
So he has body pain, no one interacts with him or wants to stay in the same room as him, he can't communicate properly, nor sleep or eat. Eventually the government asks Marvel to remove the curse so he can stop hiccuping, because he entered a catatonic state and tried to strangle himself to make it stop
The Justice League eventually finds out about this case and they honestly don't know what to make of it. They knew the captain would never do something harsh because he's good that way, but they were quite surprised that he managed to turn a relatively silly punishment into something that was almost torture
