Earlier in the year, Iron Man 3 toys began to pop up that first revealed a “Deep Space Suit” that, later, added legitimacy to a scoop, from Latino Review ( who are pretty legitimate as it is ), which spoiled what the Marvel threequel’s inevitable post-credits teaser will consist of tying Iron Man 3 to the upcoming Guardians of the Galaxy, additional details have surfaced revealing a possible plot point of the 2014 space epic.
According to Io9, this occurs after the Chitauri attack in The Avengers especially, maybe because Stark is now aware of Extraterrestrial life:
Tony Stark creates the “Space Suit” “using a unique new metal alloy that absorbs his ARC Reactor energy signature. Tony travels into the far reaches of space to find the source of a coded SOS he receives at the end of Iron Man 3. The SOS is from a masked Star-Lord, so Tony takes off to find him (noting that, with the space armor, he’s “ready this time”). Jarvis asks Tony where he’s going, replying, “I’ll be back.”
Considering it was previously reported that Tony Stark would also pop up during the Guardians of the Galaxy post-credits teaser, the above spoiler implies that Guardians will take place either before or runs concurrently with Iron Man 3 events on Marvel’s shared cinematic timeline. What happens in Guardians of the Galaxy that will force Star-Lord to ask for Iron Man’s help, while also leading up to the 2015 sequel The Avengers?
If you ask me Thanos is plenty of reason for a distress call!
What if Star-lord, who is from Earth, is calling to warn that the Mad Titan is coming to Earth? Not as Cool as Silver Surfer Crashing through Dr. Stranges window ( Infinity Gauntlet ) to do the same, but still.
Then the Avengers sequel begins.
