The new trailer for Avengers: Infinity War from the Super Bowl LII broadcast this weekend ended with an extreme close-up of Thanos that offered a more detailed look at the ugly, purple mug of the warmongering antagonist.
The sequence brought attention to a nasty scar running down the left side of his face, three deep gashes that are fairly reminiscent of another iconic character–Wolverine.
There is potential in the thought that the Mad Titan had to deal with such an injury at the mercy of Wolverine and his vicious adamantium claws. It is exactly what the fan-base of Marvel has been exploring these past few days.
Thanos has travelled across galaxies in his mission to spread chaos and subjugate worlds. Hence, the more logical explanation would be that the warlord received several scars from various adversaries over the decades and not necessarily Wolverine alone.
The theories being crafted by fans stem from the landmark deal currently on the table where Disney will be acquiring 20th Century Fox for $52 billion in the time to come. This means that the X-Men will be part of the Marvel Cinematic Universe (MCU) and Wolverine will be sharing the same world alongside the Avengers.
The problem with that theory is how the acquisition could take months or even a year to be finalized. Avengers: Infinity War wrapped up production before the deal was even pushed. Hence, there is no way that the Russo brothers decided to drop in Wolverine before the X-Men franchise was confirmed to be in the hands of its new owner.
It should also be noted that Thanos has seemingly never been to Earth in the MCU timeline. Unless there was a parallel universe where Thanos ended up fighting Wolverine, there is no way that the Mad Titan made contact. Avengers: Infinity War will be the first time when he steps foot on our planet.
To conclude, those scars were left behind by someone else and not Wolverine or any other X-Men for that matter. The mutants will ultimately find their way into the MCU, provided that the acquisition goes through, but will take several years.
Avengers: Infinity War will hit theaters on May 4, 2018. The untitled sequel, presently dubbed Avengers 4, is slated to premiere on May 3, 2019.
