I'm looking for a fic that I'm pretty sure was on Ao3 that was about Tony becoming immortal during a battle.
It's one of those 'five times ___ did___' kinda thingys and starts with Tony trying to kill himself in many ways (eg flying into a exploding earth/star), then the ways in which he tries to kill himself become less severe and dangerous (I don't remember much of this part), then finally in the last part, it reveals why Tony kept trying to kill himself by showing him in a battle with the rest of the (MCU) avengers and I'm pretty sure saving one of his teammates from an attack and becoming immortal in their stead.
I probably got some details wrong, but hopefully it's enough for someone to be able to recognize this fic!
Even if you don't recognize this fic, thank you for your time! And if you do recognize it, please, please tell me!!
Thanks so much!!!! :)
