Some other ideas I had:

What if Hulk fought Tiamut?

In behind the scenes footage, on the Sakaar set, there were posters that seemed to be promoting a fight between the Hulk and Tiamut (his original comic design). So what if Tiamut was inside Sakaar. Hulk would team up with the other Champions of Sakaar: Man-Thing, Ares, Beta Ray Bill, Dark Crawler, and Bi Beast.

What if Odin had the real Infinity Gauntlet?

What if Darryl Jacobson was worthy?

What if Fury recruited the Defenders?

What if SHIELD detected the High Evolutionary?

What if Adam Warlock wasn't born premature?

I have my 5 What If? Ideas 💡

1. What if Christine Palmer become the Sorcerer Supreme instead of Stephen Strange

2. What if Bucky Barnes become a new Captain America instead of Sam Wilson

3. What if Kang the Conqueror got out of the Quantum Realm

4. What if the Avengers were fighting Skrulls during Secret Invasion

5. What if Rocket Raccoon is going solo instead of meeting Groot and never join the Guardians of the Galaxy

Perhaps they should do an animated show on the Marvel Wastelanders?

@Walker Tom

Those two are actually genius. Some people were mad that Sam got the shield and not Bucky (Which I understand but at the same time, that's exactly what happened in the comics). Maybe we could have this version of Bucky be a recurring MCU character. But he eventually passes the shield down to Main Bucky to live a normal life.

I do feel like Secret Invasion had a lot of wasted potential. This could be a good way to make up for that.

What if Alexander the Great didn't turn on Ammit?

Alexander would continue to conquer more of the world. His enemies would consist of Moon Knight, Scarlet Scarab, Black Panther, other avatars, the Hand, the Ten-Rings, the Ancient One, the Eternals, the Black Knight, the Iron Fist, and maybe HYDRA.

What if the High Evolutionary was at Pet Palace?

It starts with Thor entering Pet Palace to find a horse. Inside is also the High Evolutionary, looking for new test subjects. The High Evolutionary recognizes that Thor is an Asgardian and is interested in learning about Asgardian evolution. The High Evolutionary offers Thor a ride back to Asgard on his ship.

On Asgard, Thor shows the High Evolutionary Sleipnir, Riding Cats, and Bilgesnipes. Thor leaves to talk to Odin about his banishment. A bilgesnipe escapes on the High Evolutionary. He tracks it to Odin's vault. There, he comes across the Tablet of Life and Time. He steals the formula and uses it on himself.

He finds Thor and offers to take him back to Earth to try and recover his hammer. He also doesn't want to be caught with the stolen formula.

Back on Earth He begins to evolve and as he gains his godly powers, he is accidently destroying the town. SHIELD responds since they are there for the hammer. He is too strong Iron Man and War Machine are called in.

Odin finds out what happens and sends Sif, the Warriors Three, Loki, and even Balder to fight.

He is still too strong, so Odin contacts the other gods for aid.

First to appear through the bifrost are Black Panther, Moon Knight (Arthur Harrow), and M'Baku (empowered by Hanuman). Other avatars could follow.

He then starts growing in size. Eventually he is punched in the face by Ikaris, who brought the other Eternals (he could prevent the birth of Tiamut with his experiments).

The gods of Omnipotence City eventually show up and fight.

Odin contemplates freeing Hela to fight but doesn't.

One of the gods yells about finding the Necrosword, but is crushed before he can finish.

Odin goes to fight, eventually pulling out the the Tesseract , crushing it, and placing the Space Stone in his Infinity Gauntlet. He fights and loses.

The Ancient One and the Masters of the Mystic Arts show up for the birth of a new god is a threat to reality.

Eventually the High Evolutionary grows until he enters a version of Overspace from the comics. There he is confronted by Those Who Sit Above in Shadow.

One ending is that Those Who Sit Above in Shadow remark how they haven't had visitors and that its too bad it wont be for long and the High Evolutionary dies because he cannot handle the power.

Another is Those Who Sit Above in Shadow fight the High Evolutionary because they don't want to share their power with a false god. He is depowered, sent back to Earth, and taken by the Asgardians. The High evolutionary wakes up inside a cage surrounded by Balder, Sif, and the Warriors Three. It is revealed the Asgardians deemed him too dangerous to be kept in one of their prisons and they are offering him to the Collector, however when the Collector expresses interest, the Grandmaster chimes in and says he'd be a great contender for his Contest of Champions.

What if the eternals interfered

What if ramonda never died

Strange never casted a spell for Peter

Monica never got trapped in the x men verse

@BabyBomber Nice scenario for Homecoming.

@RudeKaizerPrime Hydra is nowhere near that old. Wouldn’t be a good idea to make them the good guys either. Pretty good scenario for the High Evolutionary.

Ultron and Kang the Conqueror team up

@Superbattleshipyamato For HYDRA, I was going off the fact that in Agents of SHIELD they establish Hive had a cult following when he was on Earth. He was created about 5,000 years ago and Alexander the Great died about 2,300 years ago, so his cult which would become HYDRA most likely existed. Maybe it was a different organization before reforming into HYDRA. Also they wouldn't be good guys, they would be villains that don't want another villain taking over the world. I just thought it would be a cool twist ending that HYDRA wouldn't be revealed until the end. Alexander would get poisoned by one of his subjects, who would then whisper Hail HYDRA to him. But that was just one ending i thought of.
