A new fan trailer seamlessly mashes up the heroes of the Marvel Cinematic Universe with the X-Men, the Defenders and even Ghost Rider to take on the Thanos in Avengers 4.

Since Disney and Fox shareholders approved the $73.1 billion merger, fans are all too excited to see how characters like the X-Men, Fantastic Four and Deadpool mesh with the MCU.

Stryder HD's trailer for the so-called Avengers 4: Infinity Gauntlet strikes the right emotional chords, with a score that sets an dramatic tone. It calls in the X-Men and other heroes for backup in the fight against Thanos following the finger snap that wiped out half of all life in the universe.

The trailer goes further to include Ant-Man and The Wasp characters Scott Lang, Hope van Dyne and Dr. Hank Pym; Deadpool; Luke Cage, Daredevil, The Punisher and Iron Fist from the Netflix dramas; and Ghost Rider from Marvel's Agents of S.H.I.E.L.D.

Cyclops is incorporated into the battle against Thanos, as is the poignant scene in Logan between Professor Xavier and the former Wolverine. Later, Jean Grey and Captain Marvel are spotted as well.

The fan trailer also throws in an appropriate nod to Hawkeye, when he notes, "None of this makes sense," which sums up the fan reaction to the character missing from Infinity War.
