The highly anticipated first trailer for Captain Marvel was finally released earlier this month, which has now put the attention back on the fourth Avengers film and its title.
Avengers: Forever was another title, which Eternity War fits in nice with, and the Russo Brothers have admitted that fans have gotten close.
Reddit user TMKTanner recently shared his idea for the Avengers 4 theory and it makes a lot of sense.
Speculation has been swirling for months in regard to the official title of Avengers 4, and a new fan theory has proven to be the best idea so far.
