The most common human names used for him are Alfred, Allen, or Al Jones.
His physical build is similar to his counterpart's. 2P!America has dark auburn hair, tan skin and blood red/ruby eyes similar to 1P!Prussia's but without their purple tint. In several depictions, he is seen missing one of his top left incisors. Others portray him with various piercings.
His clothing consists of a leather Bomber Jacket decorated with a red star on the front, a white shirt, denim pants, and red converse style shoes with white accents.
In place of his counterpart's regular glasses, America occasionally wears sunglasses, either on his nose or on his head.
He loves carrying around his nail-filled baseball bat, which is used more for fighting than actual baseball, as it makes him appear scary and threatening. He is seen with a gun strapped to his belt in several depictions.
2P!America has a far more delinquent attitude than his 1P! counterpart. He is actively portrayed as mischievous, cunning, somewhat hot-headed, street wise, and smug. He's quick to start a fight and doesn't know when to stay down. He's cocky and somewhat arrogant, but if you talk to him privately, he is fairly soft-hearted with a love for animals. The love of animals influenced his vegan/vegetarian attitude, which most fans portray him as. He is also sometimes portrayed as a flirt, and he will call almost anyone the nickname "Doll Face" or just "Doll".
Sometimes he has personality shifts where he hates himself and constantly points out his own flaws. During his emotional spurs, he harshly views himself and compares himself to other people, mostly 1p! America, and questions why "nobody likes him". He is also loud on negative subjects and constantly whines about his problems.
2P!America is sometimes portrayed with a Boston or New York dialect.
Weakness is a pet-peeve of his. If he has an acquaintance that he perceives inferior to him (which is basically everyone), he'll be very forward in reminding them their place and actually makes it a hobby to do so.
Broadway musicals and animals are his primary interests. He enjoys the odd fight, particularly with his brother Canada, though mostly as a stress release for both of them. He doesn't like sugar like his counterpart (although he has a secret love for chocolate) and has a habit of making fun of 1P!America when the latter is trying to lose weight. Sometimes in the fandom, he is considered to be vegan (not eating/drinking animal products, like bacon or milk). He also uses a lot of profanity, although this is risky around Oliver (2P!England) due to his hatred of the activity.
It is common for the Second Player to be portrayed as murderous, sociopathic and possibly insane. To most, they are a darker version of the original Nations. However, because the Original Nations can be portrayed the same way by the fandom, how much hold this has depends on the person making the story.
2P!America is known to often pick fights with his brother 2P!Canada and imposes himself for consciously selfish reasons. There are always double-standards to his help that all end up with either a debt towards him, money making or some other kind of advantage that spreads his influence elsewhere.
In this respect, he is very much a [New York] mobster and his intelligence lies in manipulation rather than any kind of social skill.
There was a sketch released on Himaruya's blog of 2P! America. It was never official and did not become canon as the sketch was not finalized. The sketch was under the 2P!files. One concept is him with his normal hair, wearing a tank top and dog tags. He's wearing military pants and combat boots, with gloved hands holding a rifle, and what appears to be a military jacket. The other sketch is him wearing a formal suit and cape while holding a book.
