Nico

Nicole Arias, commonly referred to as Nico, tries to save the Earth from certain doom. Nico is actually Josenpai's younger, more attractive, smarter, faster, stronger, more competent, cousin, and is usually seen as the strongest character in the game. He is the only male character in the game who has the option of building a harem, as developers liked him so much they did not want to limit him to a single female character.

Stats
Nico is a medic class, but that does not mean he doesn't pack a punch At max level 30, Nico has the third highest Strength rating, right before Mum and Musclestacio (who is the highest at 3000) His Magic stat is also the highest possible in the game so far, and he has one of the highest speed ratings.

Skill: Charm
Nico can choose a target to charm, reducing their resistances to him by 50% and preventing them from attacking him. This makes him one of the easiest characters to keep alive in the game.

Skill: Counter
Nico shouts at the top of his lungs "No You"

Skill: Sing
Sings "como se mata el gusano," allowing adjacent allies to have a turn again, and rooting adjacent enemies, preventing them from moving the following turn.

Skill: Smug Zone
Sends enemy into the smug zone.

Dr.Nico
Nico makes his Super Smash Bros. debut as a trophy, seen wearing his downloadable Dr.Nico skin. He is rumored to be a playable character in the upcoming game, but many say his character would be too powerful to fit in to the fighting game

Pantsu
Overwatch developer Blizzard has actually stated that popular character Torbjorn was actually based off of Nico. They point to similarities in attractiveness and popularity, and state that they are big fans of him in the game series. They said due to copyright issues, they were not able to add him directly to the game, while another developer said that it was actually due to difficulties balancing the game if he was to be added. Instead, they added his character, shrunk him to half his size, and gave him a hammer and turrets.
