Avengers: Doomsday final trailer was just released, and the date of December 18, 2026 is the confirmed release date. The final trailer shows Victor Von Doom blocking a fully powered Thor with Stormbreaker with minimum effort. The same weapon was able to penetrate Thanos's armor, signifigying a strong increase in power from Thanos to Doom. Doom largely operates on his own with robotic droids, while Thanos commanded an army. That being said, lets get into the rankings.
12. Doctor Doom

With no hair to show, he is not brave enough to show even a flawed hairline. Last place.
11. Professor X

He's Bald.
10. Magneto

Old, thin, gray
9. Captain America

Too basic of a haircut. Not bad, but a lot of competition on the list.
8. Ant Man

From the looks of it, the guy needs a haircut. Kind of just one tone all around
7. Steve Rogers

Nice length but flat looking, not many layers, oily instead of a natural shine, and not much depth.
6. Thor

Well groomed, nice and short with some texture on top providing some depth, would like to see a different hairstyle though from this Viking. Just seems a bit too clean cut for the character.
5. Gambit

Nice to see Channing Tatum grow hair out, assuming its not a wig. The trailer was too dark to make out specifics, but the overall thickness and style was very nice. Very close to the Xmen show of the 90s.
4. Reed Richards

Pretty iconic looking salt and pepper look with the gray sides and the dark top. Very bold to keep the gray and embrace the age while keeping things interesting.
3. Shuri Black Panther

Amazing braid work. Combat ready but also very stylish. It embodies Wakanda while maintaining her femininity. T'challa had short hair, while she chooses to keep her hair long and not compromise for the armor or combat.
2. Mystique

A really dramatic undercut with long heavy locks on top create an awesome flow that doesn't look to helmety. A great balance of a feminine haircut that can also have an intimidating factor to it.
- Bucky Barnes

Didn't get much time in the trailer, but appears to have a nice thick mane on top and the sides are long, layered, and well groomed. Reminicent of the Winter Soldier, but much more styled. Maybe its a symbol of both parts of him being required to take on this powerful foe in Doctor Doom.
