FUN WAYS THE MCU CAN START INTRODUCING X-MEN ELEMENTS (NOT INCLUDING WANDA VISION):
Guardians of the Galaxy Vol.3
Mentions of the Starjammers- a team of space pirates led by Corsair AKA Christopher Summers who is the father of Scott Summers/Cyclops, Alex Summers/Havok, and Gabriel Summers/Vulcan.
Introducing the Shi’ar, a very importance alien race in the X-Men mythos. In fact, Professor Charles Xavier actually has a daughter (kind of), Xandra Nermani, with a member of the Shi-ar royal family, Lilandra. Lilandra’s sister, Deathbird, was is married Vulcan and pregnant with his child.
Black Panther 2
Ororo Munroe/Storm- An omega-level mutant once worshiped as goddess, Storm and T’Challa were once childhood sweet-hearts and were actually married for sometime -making Storm queen consort of Wakanda- in the comics before divorcing due to a number of factors including working long hours and the Avengers being dicks to the X-Men. Storm was the first major female character of African descent in comics and is regarded by many as being Marvel Comics' most important female superhero so even a mention or allusion to her would be awesome.
Namor- There have been a lot of talk about Namor showing up in, or even being a villain, in BP2 and that would be an excellent introduction of King of Atlantis into the MCU. Namor is half-mutant and half-atlantian so he tends to have an interesting relationship with the X-Men which can best be summed up as -he doesn’t hate them as much as he hates other surface dwellers. In fact, Namor even developed quite the endearing relationship with the Young X-Men member Loa, whose grandmother he was friends with. It was even hinted that Loa herself was actually Namor’s granddaughter.
Adamantium- Most famous as the unbreakable substance that coats the Wolverine’s bones, adamantium was created in a lab by Dr. Myron MacLain for the government in an attempt to reproduce the vibranium alloy he had made for Captain America's shield. It is stronger than vibranium but not nearly as versatile. Considering Shuri’s own genius, it would make sense for this metal to be metaled.
Gentle- Nezhno Abidemi was the son of a Wakandan woman and a Russian man. All his life Nezhno was persecuted and rejected, even by his own mother, because his father was an outsider, and it was from him whom Nezhno inherited his X-Gene. Nezhno was raised at the Royal Court of Wakanda. When his mutant powers manifested, Ororo Munroe, the new queen of Wakanda, advised her husband King T'Challa to send Nezhno to the Xavier Institute learn how to control his powers. It would be kind of neat for the one of the first mutants in the MCU to come from Wakanda.
The Falcon and the Winter Soldier
Weapon Plus Program- Within the MCU, the Weapon Plus Program is an attempt by the US Government to recreate the super solider serum the created Captain America that eventually led to the creation of the Hulk and the Abomination. However, this program would go through several iterations with Weapon X is the tenth iteration of the Weapon Plus program. Weapon X’s most (in)famous creation would be the Wolverine.
Bucky’s Flashbacks- Logan AKA the Wolverine is an OLD man and fought in many wars, including WWII. On several occasions, Logan fought alongside Captain America and Bucky... sometimes they even rescued a young Magneto from the concentration camp he was trapped in.
Doctor Strange in the Multiverse of Madness
America Chavez- While not confirmed, it is suspected that America Chavez AKA Miss America will be in Doctor Strange 2. One of Chavez powers is the ability to open doorways to other dimensions so perhaps, with these powers we can see dimensions such as Limbo (a hell-like dimension ruled my New Mutant character Illyana Rasputin/Magik) or even the infamous ‘Punch Dimension,’ from which (according to some sources) Cyclops optic beams come from.
The Eternals
Origins- LOOOOOONG story short, the experimentation on primitive humans that created the Eternals also gave humans the capacity to become mutants, meaning that the two groups of characters are definitively linked by a shared creator. Specifically, the X-Gene was engineered by Oneg the Prober (whose name I really hope they change).
Black Knight- The Black Knight that will be appearing in the film, Dane Whitman, is the latest in a long line of warriors to wield the cursed Ebony Blade and one of the previous Black Knights was a man named Eobar Garrington who was various close friends with the omega-level mutant Bennet du Paris/Exodus, who would grow to become one of Apocalypse’s greatest servants. Perhaps a family story or two would make mention of this fearsome creature.
Apocalypse- Speaking of the Mutant Immortal, the Externals are likely some of the only beings old enough and strong enough to have met old En Sabah Nur and can still talk about it. Also, part of what makes the Big A such a threat is his access to Celestial technology, including a snazzy set of armor. Oh the stories they could tell...
