10 Things Everyone Gets Wrong About The MCU
3. Nobody Ever Stays Dead
Characters that aren't called Uncle Ben rarely stay dead in comic books, and some have claimed it's a similar story in the Marvel Cinematic Universe where the likes of Nick Fury, Pepper Potts and Groot have all been given faux demises.
Although the MCU hasn't been afraid to kill off the occasional villain, there are those who believe the good guys are virtually untouchable, and that isn't the case: just ask Odin, Peggy Carter and Quicksilver.
Okay, so those three are basically B-listers, but given that one is a god and another a superhero, Marvel Studios has demonstrated the mortality of its characters, and this is a theme that will be explored in a deeper way in Infinity War.
You can't have a war without casualties, and it's safe to assume the ones Thanos will inflict are going to be permanent to pave the way for a very different Phase 4.
