The Marvel epic’s ending saw our heroes in a bit of a pickle.
Just how in Stan Lee’s name are they going reverse Thanos’ Snap?
Well on popular idea sees the surviving Avengers collecting the Infinity Stones through time.
However a new theory suggests they will instead harness weapons of their own that could match the power of the Infinity Stones in Avengers 4.
Reddit user bluecoloredlenses argues: “There is a common theory that Stark goes back in time and collects the Infinity Stones, but I think it is more subtle.
“I think they’ve been building their own set of “weapons” with the same capabilities in their own way, and that we’ve seen it colour coordinated throughout, with each series developing one.
“Black Panther, Heart Shaped Plant, purple and grants increased strength -> Power Stone.
“Thor, Stormbreaker, blue lightning and now has Bifrost abilities -> Space Stone.”
They continued: “Ant-Man, Pym’s Time Machine (theory), Quantum Realm was green when visualised -> Time Stone.
“Iron-Man, Vision, Jarvis’ brain was yellow when visualized -> Mind Stone.
“Captain America and Hydra, gave Wanda her powers, her power “reality warping” is red when visualised -> Reality Stone.
“Doctor Strange, channeled mystical energy, spells are visualised as orange -> Soul Stone.”
The theorist added: “The Guardians series didn’t generate one, but Gamora’s life was obviously important.
“One specific thing that brought this to mind was re-watching [Avengers: Age of] Ultron and being reminded of how Wanda could hijack people’s minds just like the Reality stone and the obvious red colouring.
“Hulk might tie in a bit with the time machine’s development, double up on the green factor.”
Avengers 4 is released in UK cinemas on April 26, 2019.
