If all my OC’s were ending up fighting, who would be the only one to win? (Read description and argue your answers please)

This isn't about powers, abilities or anything else.

It's about pure fighting skills.

Two rules tho:

1- You need to argue your answers

2- Cyan can't be said since bro is op in fighting skills too. Glitch can't also be said since she's literally….a virus.
