This was a fun question to ponder!! For me it’d be:
Miki: Because she’s not only physically powerful, but she has a huge amount of stamina, and she’s highly intelligent as well. She thinks quickly and formulates the best plan for anything thrown her way.
Raiden: He’s allll muscle, and he’s trained to perform cold assassinations. Once he’s got a specific target, it’s hard for him to think of anything else.
Then Kimiko: She’s quick on her feet and isn’t distracted easily, not to mention she has zero qualms of meeting an enemy head on. She also trains incredibly hard each day, at least 3-4 hours a day.
1st: InuYasha ofc. A main character with a freaking strong sword and other abilities 2nd: Shessomaru. The demon who could be only beaten by InuYasha 3rd: Strange enough, but Sango. A demon-slayer girl and the only human who fights without special abilities, yet manages to keep up with everyone.
Mazuki Uchiha (She's a cross character) pretty much because she was trained/raised by Madara, then later traveled to the DBZ universe and met Beerus the Destroyer he trained her afterwards, and is about the rank of a god of destruction.
Natsumi (Dbz character, daughter of Mazuki and Vegeta) She was entirely trained by Whis, and reached SSJ3 by age 9.
Skylar Johnson (Marvel OC) She was taken in by Mephisto, and was granted many gifts. She sadly sold her soul to him, and was betrayed, but she escaped his rule and lives on earth, she is capable of shape shifting, teleportation, and telekinesis. She also has hellcats, which have a base form of a domestic cat, then transform on her will into these feline-like beasts that are big enough for her to ride.
