10 Shocking (But Believable) Theories About Marvel's Phase 3

4. The Defenders Will Join The Fight - Avengers: Infinity War

Well, here's a theory that absolutely everybody wants to come true, because how awesome would it be if The Defenders - the soon-to-be teaming up heroes of Marvel's TV shows exploits such as Daredevil, Luke Cage and Jessica Jones - came together with the Avengers and the Guardians to battle Thanos in Avengers: Infinity War? "More awesome than words" is the reply you're looking for, and there's good reason for that: with a cosmic battle on the horizon, the more heroes the better, and this theory not only makes sense - after all, wouldn't everybody with powers need to help out? - but would bring together the MCU and its TV equivalent in a way unlike anybody has seen before. Going by the timeframe, The Defenders will probably band together around the time that Infinity War hits cinemas, which would make a crossover kind of perfect. And after the success of Daredevil, nobody is worrying about a clash in quality levels (that was a problem that only applied to Agents of S.H.I.E.L.D.) So whilst some might deem the addition of the The Defenders a step too far, this is theory that still carries some weight.
