What if is an animated series from Marvel Studios that reimagines certain characters and events in the Marvel Cinematic Universe? The MCU. Now it deals with certain things that has not happened, but could have been like, what if Peggy Carter had taken the Super Soldier serum instead of Steve Rogers? What if Tichalla became Star Lord instead of Peter Quill? What if Killmonger saved Tony from the blast in Iran? Sounds like the Avengers would have never existed now in the first place. Right?
