5. Old Man Logan
First appearance: 2008 in Wolverine (Vol. 3) #66
You might think that we already got this Wolverine in the film Logan, but this is only very loosely based on the comic character of the same name. The original Old Man Logan
killed all X-Men due to a trick by Mysterio. After that, an apocalypse followed, and he withdrew as a farmer in Hulkland.
There he lives with his family but has to pay taxes to the Hulk family. When money gets tight, he goes on a mission with Hawkeye. Wolverine no longer fights back after what he has done to the X-Men. He hasn’t extended his claws in years, but ultimately he has to do it. (Source: Old Man Logan Deluxe Edition)
This story of Wolverine is grim, very grim. Many of the heroes you know are dead, and even the Hulk is not the one you know anymore. It is an exciting story, but it has too many different figures for a film. Also, with Logan , there was a film that has a similar message at its core.
You can also find more X-Men action in this series:
4. Hydra-Wolverine
First appearance: 2007 in Exiles #92
Madam Hydra is a high leader of the terrorist Nazi group Hydra
from the Marvel Universe. In this universe, however, it is Sue Storm who is with Wolverine and no longer with Reed Richards.
Hydra-Wolverine is dressed in green and wants to subjugate the entire multiverse with his beloved. However, he is ultimately killed by a variant of Kitty Pryde, and his rampage is stopped. (via Marvel Database)
It is very unlikely that we will ever see this variant on the big screen. Hydra is used more as a secret but grounded organization in the Captain America films, rather than a threat to the entire multiverse.
3. Old Man Phoenix
First appearance: 2017 in Marvel Legacy #1
In Earth-14412, James Howlett was killed when a powerful variant of Loki wiped out all of humanity. However, the Phoenix Force, a powerful entity that chooses hosts and grants them incredible powers, revived him.
Outside time and space, he then traveled and addressed several issues, such as the Celestials and the Infinity Stones, which only caused suffering. He fought against several well-known villains like Doom, Ultron, or Loki. Later, he even joined an Avengers team led by the goddess of thunder. (via Marvel Database)
It is quite unlikely that we will ever see someone other than Jean Grey with the Phoenix Force. The Phoenix Saga has been adapted twice, and without current X-Men, such a dimension of a story cannot be expected in the near future. However, it would be possible in anthology series like What If…?.
