Sneck

"Biting Snake Fist" Sneck (蛇咬拳のスネック, Jakōken no Sunekku) is an A-Class Superhero, rank 38. He was tasked with welcoming the new heroes for the National Superhero Registry Test that Saitama and Genos were a part of.

Appearance
Sneck is a tall and very serious looking man with a rather angular face and sharp eyes, and has spiky black hair. He wears a snakeskin suit with a black dress shirt, white tie, and a pair of black shoes.

Personality
Sneck is a rather pretentious individual, thinking that people who are new to the Hero Association should respect him. Also, he takes the rankings of the association very seriously, attempting to assault newcomers who have the potential to be better than him, especially if they don't take him seriously. This implies a slightly corrupt motivation for being a hero.

National Superhero Registry Arc
Sneck was tasked with welcoming aspiring superheroes to the Hero Association, and provide the aspirants an orientation on what to expect from the job. He quickly began to regard Saitama as someone who shouldn't belong there, and fully expected him to fail in the application tests.

Sneck was very surprised to learn that, while Saitama did not do well in the written tests, he set new records in all the physical exams. In outrage and disbelief he challenged Saitama to a duel to break him in and show him the pecking order in the Hero Association. The scene then shifts to reveal Sneck lying defeated in a heap as Saitama nonchalantly walks away. Sometime after the event, he received a promotion to rank 37.

Rumored Monster Arc
Sneck is briefly seen during a meeting held at the headquarters of the Hero Association. It is revealed that he is in charge of F-City. He reports that Hammerhead was seen in the city walking around in a formal suit. He says that he will try to find out what Hammerhead is up to.

Sea Monster Arc
After Sea King breaks through the wall of the Shelter in J-City, Sneck steps forward alongside several other heroes to attempt to hold off Sea King. He then watches as Sea King proceeds to stab the hero Jet Nice Guy. Sea King then throws a punch at the group of heroes, hitting Buzz-Buzz Man and All Back-Man. Sneck manages to dodge the blow by jumping backwards, but in midair gets hit by another punch from Sea King, sending him flying across the shelter.

Centipede Arc
Sneck's name appears as a participant in the Super Fight martial arts tournament in C-City, although his name goes unrecognized by Saitama.

Abilities & Powers
Being an A-Class hero, it is presumable that Sneck is a skilled fighter. His preferred form of combat appears to be hand-to-hand martial arts. The Hero Association also left him in charge of F-City indicating that his prowess is recognized. Sneck is, however, the lowest ranking A-Class hero, and hid in the shelter with other heroes during the Sea King's rampage, coming out only to stand with them to fight against the Sea King.

Fighting Style
Biting Snake Fist (蛇咬拳, Jakōken): Sneck is a martial artist who uses the Biting Snake Fist style. When he attacks, the image of a striking snake appears around his hands. His capabilities with it are unknown as he was defeated by Saitama before he was able to connect.
