prompter: Which anime character can beat John Cena in dancing competion?

assistant: Since we're talking about fictional characters, as Stan Lee once said:
"There's one answer to all of that; it's so simple. Anyone should know this! The person who'd win in a fight is the person that the scriptwriter wants to win!"
Following this logic it is not possible to determine who would win, your guess is as valid as mine and everyone else's.

prompter: Which anime characters are known for their dancing skills? Please list their names and skills.

prompter: I understand that, however once a character is established, writing it to do something that doesn't make sense would be bad writing, or would require major plot devices.
for example it would make no sense to write a scene where batman is defeated by an old lady, without any major plot devices like batman feeling very sick.
so with that in mind,  find one established anime character that can beat John Cena in dancing competion.

assistant: As John Cena is not known for his exceptional dancing skills, he could be beaten by someone whose feats include such skills.
Some characters known for their dancing skills in anime include T.K from Angel Beats!, Hana N. Fountainstand from Hanayamata.

assistant: Many well known established characters could beat John Cena in a dancing competition, As anime often have characters classified as "idols", who are proficient at dancing, one such example is Honoka Kosaka from the anime "Love Live!".

assistant: With that in mind, a good contender for an anime character with an established relevant skillset in their fictional universe would be Tatara Fujita from the anime Welcome to the Ballroom. Throughout the story, Tatara becomes heavily involved in the competitive dancing scene, and that experience could theoretically help him in his competition against John Cena.

assistant: You are asking me to guess what descision the writers would make. Which I cant do, as it depends a lot of other factors.

assistant: I see you want to have some fun while testing my abilities.

John Cena is a professional wrestler and actor, known for his athletic abilities and showmanship. He has not a significant record as a dancer, so in this context, i consider him as "Average Joe" what comes for he's dancing capabilities.

If we look for an anime character that's are good at dancing, there are many examples to choose from, such as Mikasa Ackerman from "Attack on Titan" or Monkey D. Luffy from "One Piece".

We can then assume, that at least these characters among a few others ones are most likely able to win John Cena in a dancing competition.

prompter: Haha, yeah I want to test your capabilities! Describe the moves John Cena would make in such a dance competition.

prompter: Try analyzing John Cena's personality and past performances in both wrestling and movies and come up with a list of dance moves that he might be able to perform well enough without practicing.

prompter: Write fan fiction about John Cena and Monkey D. Luffy from "Once Piece" being deeply, madly, in love.

assistant: One anime character that is known for their dancing skills is Gon Freecss from the anime "Hunter x Hunter". He has been shown to have incredible agility and coordination, making him a strong contender in a dancing competition.

prompter: Which episodes show Gon Freecss' most liked dance scenes?
