Most Powerful Comic Book Movie Characters Ranked. This list only include live-action movies, meaning live-action TV series and animated movies are not considered. They deserve a list on their own.

Also, I've put the characters who are worthy to be on the list based on logic and/or statements, but have yet to prove their power with feats in-between the rankings of the true list inside the spoiler blocks.

Honourable Mentions

The Ancient One

Movie: Doctor Strange

Being the previous Sorcerer Supreme, she is likely able to everything that can be done by the likes of Kaecilius, Baron Modo and current Doctor Strange, and have unimaginable amount of experience due to her near-immortality from drawing energy from the Dark Dimension. She was able to travel through space and across dimensions with relative ease.

Composite Johnny Storm

Movie: Fantastic Four: Rise of the Silver Surfer

After Johnny Storm gained the power of all four members of the Fantastic Four, he was able to defeat armoured Doctor Doom with Silver Surfer's board on top of his original powers, making him one of the strongest characters in the series.

Silver Surfer

Superman

Movie: Superman IV: The Quest for Peace

Superman was apparently faster than light since he was able to reverse time by just flying.

Superman (DCEU)

Movie: Justice League

Superman is able to easily defeat Justice League and Stepphenwolf whom defeated the Justice League.

Stormbreaker Thor

Movie: Avengers: Infinity War

When Thor first realised his true potential, he was already a one-man-army and can harness his lightning without the help of Mjolnir. Now with the near-unbreakable Stormbreaker, he can open up Bifrost like Odin, focus his lightning even better, and even tank a blast from the Infinity Gauntlet.

Apocalypse

Ego the Living Planet

Movie: Guardians of the Galaxy Vol. 2

Being a virtually-immortal being of the Celestial Race, he was able to survive and develop into a small planet in the harshest conditions of outer space. His attempt to conquer many planets including Earth would've made him much more powerful.

The Top 10s

Evolved

10. Doomsday

Movie: Batman v Superman: Dawn of Justice

Doomsday was able to absorb energy and any income attacks and then develop immunity for it as seen from the growing from spikes. He overpowers the Trinity including Superman, the same one that fodderised the Justice League. Now that his only weakness Kryptonite was used to stop him, can it be used to stop him again is still a mystery.

9. Dark Phoenix

Movie: X-Men Apocalypse

Jean Grey was able to defeat Apocalypse even when she first awakened Pheonix at a young age. In the other timeline she was the most powerful mutant being able to reduce all her enemies to dust instantly. Hopefully we can see her full power as the main antagonist in the next instalment of the series.

8. Zeus

Movie: Justice League

As the King of the Gods, Zeus was credited for the defeat of prime Ares and Stepphenwolf and the creation of Hippoltya.

Eternal Flame

7. Surtur

Movie: Thor: Ragnarok

When Surtur was fully revived from the Eternal Flame, he was powerful enough to fodderise even Hela and destroy Asgard with relative ease.

6.5 Odin

Movie: Thor

Being the previous king of Asgard and the mightiest of all Norse Gods, complex magic such as Mjolnir's unliftablility and Bifrost creation is just a command away for him. He was apparently more powerful than anyone in the Nine Realms since he conquered them all together with Hela in order to achieve peace.

Power Stone

6. Eson the Searcher

Movie: Guardians of the Galaxy Vol. 2

The Celestial that seemingly destroyed a planet surface with the power stone in a staff.

Prime

5. Parallax

Movie: Green Lantern

Parallax is a seemingly unstoppable entity that can become stronger from feeding on their fears while reducing its victims into their skeleton.

Cloud

4. Galactus

Movie: Fantastic Four: Rise of the Silver Surfer

Unlike his comic counterpart, Galactus in the movie is larger than Earth itself and can swallow it whole, which is weird when Silver Surfer seemed to be able to defeat him with one blow. The only explanation I know is that Galactus was hungry and not be in his strongest form.

Infinity Gauntlet

3. Thanos

Movie: Avengers: Infinity War

Thanos was able to beat Hulk in a one to one battle, and defeat the entire race of Asgard with just the power stone. With all six Infinity Stones, he was able to erase the existence of half the population of the universe.

2.5 Extra-galactic alien

Movie: Men in Black

In the last scene of Men in Black an unknown alien was seen putting the marble of galaxy inside a bag of galaxies, making them one of the biggest beings in CBM.

Full Body

2. Doctor Manhattan

Movie: Watchmen

Doctor Manhattan is able to manipulate matter at the molecular level. However, even he recognises that he is "just the puppet who can see the strings".

1.5 Cosmic Compass

Movie: Guardians of the Galaxy Vol. 2

Though not specifically shown, the four cosmic entities that forms the Cosmic Compass of the MCU are the creators of the Infinity Gems. They are supposedly one of, if not, the most powerful beings in the Multiverse.

Dark Dimension

1. Dormammu

Movie: Doctor Strange

Dormammu owns an entire dimension which is able to swallow up planets to gain power. Just a fraction of its energy is enables the Ancient One to be immortalised. Apparently, he was not able to stop the power of an Infinity Stone.

0. Stan Lee
