The DCEU version of Wonder Woman has continuously proven that she is amazingly powerful. Breakdowns of her feats easily scale her near the DCEU Superman's level as she is seen swatting away bullets with ease, blocking light speed attacks, redirecting God-level lightning strikes, and easily lifting a tank weighing several tons.
She also has access to some amazing equipment that is seen maiming Doomsday, deflecting attacks that would have shattered Captain America's shield, and producing energy blasts that even Superman seems to take seriously as he prevents her from unleashing such a blast from her bracers when he is resurrected. On top of all this, she also has endurance, regeneration, stealth, and willpower. Many anime characters would prove to be a problem for her in a fight.
Could Beat Her: Ikaros
Ikaros is a Battle Class Android from Heaven's Lost Property. Ikaros has a large variety of amazingly overpowered abilities including a near-invincible shield, a bow that destroys countries with one arrow, and a flying speed of Mach 24.
While these abilities are all very impressive and would likely be enough to beat Wonder Woman, Ikaros's greatest power comes in the form of transport cards which grant just about any wish seeming to literally reshape the fabric of reality.
Couldn't Beat Her: Deku
Deku is the hero name of the main protagonist from My Hero Academia, and he's pretty impressive for being a hero in training. If he was able to use One for All at full power it is unlikely Wonder Woman could beat him.
Yet, at 20%, Deku simply doesn't have the power required to do any lasting harm to Wonder Woman nor does he have any viable method for combatting her more than formidable equipment.
Could Beat Her: Ryūko Matoi
Ryūko Matoi is the main protagonist from Kill La Kill and, by the end of the anime, she has unlocked some pretty incredible powers. Her regeneration and durability are off the charts due to the nature of her body. She has the ability to rapidly gain strength, speed, and fighting skills in order to overcome the odds and is equipped with scissor blades that can cut even life fibers.
Even with all of this power, though, a fight with Wonder Woman would test her more than any fight before. Yet, her ability to evolve is what truly makes her a force capable of defeating Wonder Woman.
Couldn't Beat Her: Mikoto Misaka
Mikoto Misaka is the main protagonist of A Certain Scientific Railgun and her electrokinetic powers provide her with a wild amount of shockingly powerful abilities. Unfortunately for Misaka, Wonder Woman has been shown easily redirecting Zeus's lightning, a power that ripped apart the Mother Boxes far easier than the combined physical strength of Superman and Cyborg.
Misaka, with her electrical attacks mostly nullified by Wonder Woman's equipment, doesn't have the physical capabilities to take down Wonder Woman in a direct confrontation.
Could Beat Her: Tokimi
Tokimi is one of the three goddesses that created the universe of Tenchi Muyo. Her power level is easily universal as she can reshape entire galaxies with but a thought.
That puts her on a level of power and capabilities that is almost unmatched in any story. While this fight would be goddess vs. goddess, Wonder Woman is honestly completely outclassed despite her impressive array of powers.
Couldn't Beat Her: Klaus
Klaus is the leader of Libra from Blood Blockade Battlefront and this hard-hitting brawler has a massive list of techniques that he uses to crush blood breeds all over the streets of Salem's Lot. His techniques usually take the form of massive red crosses constructed from his own blood. While Klaus is seen easily holding his own against some pretty absurd monsters, when it comes to a fight with Wonder Woman he is at a major disadvantage.
Klaus may be able to match Wonder Woman in the strength department, but the Amazonian Goddess has him beat in speed, equipment, and endurance.
Could Beat Her: Tornado
Tornado is the second-ranked hero from One-Punch Man and the only thing deadlier than her psychic powers is her personality. Tornado has been seen using her abilities to instantly stop and redirect a large number of massive missiles without breaking a sweat and this is one of her less impressive feats.
Wonder Woman has her beat in many categories but Tornado's incredible mental abilities easily make up for these weaknesses. It's hard to imagine being able to stick a sword through a woman who can send you hurling into space with but a thought.
Couldn't Beat Her: Kirito
Kirito is the main protagonist from Sword Art Online and, by the end of Alicaization, he's unlocked some god-level abilities. Yet a great amount of his strength comes from his ability to push through the limits of whatever game he is in.
If it's assumed that Wonder Woman is fighting Kirito in-game, then it can be assumed that Wonder Woman would also be a situation where she could use her sizable willpower to also gain a massive power boost. Thus, with these two fighting on even footing, Wonder Woman has a massive advantage due to her fighting experience.
Could Beat Her: Kefla
Kefla is a character from Dragon Ball Super who is created through the combining of two Saiyans from Universe 6, Caulifla and Kale. While they were putting up a great fight against Goku separately, when combined they become utter monsters that Goku is only able to beat through once again achieving Ultra Instinct.
Considering that Goku can fight at speeds faster than the speed of light and literally threatened to destroy reality with the strength of his punches against Beerus, and considering Kefla can match this strength, Wonder Woman doesn't stand a chance.
Couldn't Beat Her: Orihime Inoue
Orihime is one of the main characters from Bleach. She has a heart of gold and the ability to reject any physical phenomenon. While this power is very impressive and is amazing for healing, it doesn't make for the best offensive weapon.
While Orihime continues to grow and developed her powers in the manga, the level she is at by the end of the anime is no match for Wonder Woman.
