A

A (エー, Ē) is a hero for the Neo Heroes and formerly a criminal with an A-Class level bounty placed on him by the Hero Association. He used to work as a hired assassin, but would also kill random people outside of his paid targets. His goal is to kill as many people as he can before he dies.

Appearance
'A' is a relatively average-looking man with messy hair. He wears glasses and a shirt.

Personality
'A' appears to be a calm and kind individual, evidenced by when he showed concern for Solitude after the latter attempted to attack Suiryu but was blown back. However, given his reputation as a killer, this kindness could be a facade. According to him, he doesn't take pleasure in the act of murder, but merely does it as a "game" to see how many people he can successfully kill before dying. His cruel nature disgusts even fellow assassins such as Speed-o'-Sound Sonic, who claimed he is more rotten than the criminal underworld.

Neo Heroes Uprising Arc
'A' is first introduced at the Neo Heroes leader meeting when he asks Solitude if he's okay after the latter gets knocked back by Suiryu. After McCoy introduces him as an A-Class criminal who specializes in monster techniques, Child Emperor states that he's probably only here because the Neo Heroes will protect him from criminal prosecution, to which McCoy responds that reforming criminals will be to their advantage.

Later on, 'A' is seen easily defeating a horned monster. Double Hole and Feather recognize him as a wanted criminal and attempt to accost him, but 'A' cryptically threatens them if they get any closer, stating that accidents happen during hero work.

Abilities and Powers
'A' is an effective fighter, earning himself an A-Class bounty and being noted by McCoy to have a fighting style specially suited for monster killing. His Neo Hero suit significantly increases his already impressive power, allowing him to kill a horned monster with relative ease. However when fighting S-Class criminal Speed-o'-Sound Sonic, he and his Neo Hero comrades were completely outclassed.

Equipment
Neo Heroes Battle Suit: 'A' wears a Neo Heroes Battle Suit, which provides him with a variety of functions. Bladed Staff: 'A' wields a staff with two blades perpendicular to the shaft on one side.
 * Mobility Analysis: The suit analyzes 'As nervous system and body, with its synthetic muscle reacting accordingly and enhancing his physical abilities.
 * Life Support System: The suit contains a life support system, although it can be damaged beyond function.

Remote-detonated bombs: A uses several remote-detonated bombs during battle to defeat his enemy or escape.
