Fantasy TV shows typically have a few characters who stand out as the most powerful members of the cast, if not one of the most powerful characters in fiction in general. These characters are unstoppable forces who drive the plot through magical ability as well as charisma. The best-written powerhouses will have character arcs where their power is used to emphasize the story and its key themes, which may focus on how unlimited power will change a person.
In several cases, the true extent of a character’s power is never (or has yet to be) revealed. This characterization has a dual effect because it leaves the audience and other characters wondering if they are hiding more power, or if they are already at their limit. However, when they are never defeated in battle and do things that other characters think are impossible, they are inevitably deemed to be one of the most powerful fictional characters.

Moiraine is one of the most skilled users of the One Power, and therefore one of the most powerful characters in The Wheel of Time. She loses this ability in Wheel of Time season 1’s ending but regains it in season 2. Members of her party or her enemy might be able to outmatch her with sheer force, but she demonstrates some more specialized weaves, especially in the Wheel of Time books. She proves herself to be a powerful manipulator of the elements during battles, and can also heal people.
10 Reasons Fantasy TV Shows Are Still So Hard To Adapt (Despite Fantasy Being Huge Right Now)

9 Alastor

The true nature of Alastor’s power is a question for Hazbin Hotel season 2. In season 1, he easily defeats everyone in Hell and is an equal opponent to Adam, one of the most powerful angels in Heaven. Alastor can also summon shadow creatures to do his bidding. However, Alastor’s brilliant scheming is what makes whatever supernatural resources he has effective: He seems to think that he cannot defeat Lucifer or one of his family in an outright battle, so he befriends Charlie and manipulates her relationships with her parents. This way, Alastor’s magical abilities will have the most impact.

Melisandre’s power is a bit unreliable and dependent on the will of the Lord of Light. However, she is formidable, being able to resurrect the dead and create a fire barrier to protect Winterfell. Her magic is vague, which contributes to her allure: Because it is based on faith and is not an exact science, no one knows the extent of it. For all the Game of Thrones cast knows, Melisandre can accomplish even more impressive feats than she ever did during her time on the show.

When Aang is in the Avatar State, he is a nearly unstoppable force. The only caveat is that he can be killed without being reborn in this state, and is almost by Azula. However, Aang’s power grows throughout Avatar: The Last Airbender as he masters all four elements and gains more control over the Avatar State. The true testament to his power is that he finds a way to defeat Ozai without killing him, which no one thinks is possible.

The Witcher season 1 depicts Yennefer’s education, setting her on the path to becoming an unbeatable sorceress. Yennefer is undoubtedly one of the most powerful characters in The Witcher, taking on an entire army at the Battle of Sodden Hill. Ciri may surpass Yennefer in the future, but Ciri gives up her powers in The Witcher season 3 finale and does not have as much control over her magic as Yennefer. As it stands, they are both among the most powerful Sources, who can channel Chaos and have devastating effects.

Wanda is considered one of the strongest characters in the MCU, with seemingly limitless telekinetic abilities. However, what she does in WandaVision is unprecedented. She alters the memories of an entire town, bringing the people under her control, and creates a constantly shifting alternate reality.
Then, in Doctor Strange in the Multiverse of Madness, she takes on an entire army of magic users. Wanda obviously does not use her power in the most ethical ways, but she is a fascinating character. Her indomitability is revealed to be because she had some inherent power of her own before it was activated by Hydra’s experiments with one of the Infinity Stones.

With every new season of The Vampire Diaries, Bonnie learns to use magic in a new way. She holds off Original vampires, revives Jeremy twice, and clings to the world of living for seasons after her death. It might be luck that she never truly dies, or it is Bonnie herself, and her connections to people like her grandmother and Jeremy.
In the final season of The Vampire Diaries, Bonnie creates an otherworld for Enzo to inhabit, holds back hellfire (with help from her ancestors), and breaks Elena’s sleeping curse. However, there is more to her story than just getting better at using magic. Bonnie is one of the most powerful characters in fantasy TV, but this facet of her character is also used to serve her emotional storylines.
