Nymphadora Tonks is also a great candidate. She's a Metamorphmagus, which means she can change her physical form. In hand - to - hand combat in fanfiction, she can use this ability to surprise her opponents. For example, she could suddenly make her limbs longer to reach further or make her body more flexible to dodge attacks more easily.
In some fanfictions, there could be a fight between Hermione and Bellatrix Lestrange without wands. Hermione, being the intelligent witch she is, would use her knowledge of pressure points and self - defense spells she's adapted into physical moves. Bellatrix, on the other hand, would be more wild and unpredictable in her attacks.
Well, in a Cissnei Hand to Hand Combat Fanfic, the author could explore her backstory related to her combat abilities. Perhaps she was trained in a secret martial arts academy. The fic could also include how she adapts her combat style to different opponents, like when facing a larger and stronger foe, she uses her speed to outmaneuver them.
Might Guy is also a top choice. He is Lee's teacher and has mastered the same style of taijutsu. His experience and his ability to open the Eight Gates make him an extremely powerful fighter in hand to hand combat. In fanfiction, he could be shown in epic battles, using his full power against strong adversaries.
One interesting scenario could be a fight between Naruto and Sasuke where they rely solely on hand to hand combat skills, without using any ninjutsu or genjutsu. It would be a raw display of their physical strength, speed and martial arts training.
Maybe it was given to him by a mysterious stranger. This stranger could be someone who has been observing Harry from afar and believes that he is the only one who can handle the power of the hand cannon. The stranger appears out of nowhere, hands it to Harry, and then disappears again without a trace.
Well, since it's a fanfic related to hand - to - hand combat, it might explore different fighting styles. Maybe it shows Cissnei in intense duels against various opponents. It could be about her journey to master certain combat techniques or her use of hand - to - hand combat in a particular fictional universe. Without reading it, it's hard to say for sure, but these are common elements in such fan - created works.
Unfortunately, I'm not aware of the author of this particular fanfic. It could be an amateur writer who just wanted to explore the character of Cissnei in the context of hand - to - hand combat in their own creative way. There are countless fanfic authors out there, and this one remains unknown to me without further research.
The story of Audie Murphy in World War II is quite heroic. Although he was a small - statured man, he engaged in hand - to - hand combat when his unit was overrun. He single - handedly held off a large number of enemy soldiers, using his wits and whatever weapons he could find, including engaging in hand - to - hand brawls to protect his comrades.
In the RWBY fanfic, Ruby could be good at hand - to - hand combat as a result of her determination and adaptability. Ruby is known for her strong will, and she applies this in learning different combat techniques. She might have realized that in some situations, her scythe might not be the most effective weapon, so she has honed her hand - to - hand combat skills. For example, in tight spaces or when disarmed, she can rely on her fists and feet. Additionally, she may have incorporated her semblance, which gives her speed, into her hand - to - hand fighting style, making her a formidable opponent in close - range battles.
