Fans are overwhelmed with excitement as the Marvel's Avengers fourth and final film of the mega franchise is coming this April. Every now and then, we have come across fans speculating new theories to how the movie plot might take turn. Fans have been speculating the appearance of Loki in Avengers: Endgame even though Thanos killed him in the Avengers: Infinity War. The Nordic God of Mischief, Loki, has previously resurrected twice in the Thor sequels, so the fans will not be surprised if he returns again. People have also been speculating that Loki took on the appearance of Bruce Banner and escaped from the ship. People have been speculating that because Bruce Banner is incapable of turning into Hulk throughout the entire run-time of the movie. The Endgame's alleged time travel plot could allow Loki to bring himself back to life. So only time will tell how much all of the assumptions will come true.
