Portgas D. Ace

Ace was much more intelligent, polite than Luffy, yet was also shown to be quite impulsive, much like Luffy, as he too would make hasty decisions and, in some cases, neglect listening to reason. . Ace is overprotective of Luffy to the point he has been dubbed to have brother complex. Ace is constantly worrying about Luffy's welfare, repeatedly saying his name and thinking about him.

Ace and his brother, Luffy, were very close as children and remained so as pirates, even after more than three years of separation. Though they were not related by blood, they were still bound by a brotherly bond. Luffy was also aware that Ace was Gol D. Roger's son. As a child, Ace was initially aloof and hostile towards Luffy. Such an example was when Luffy innocently followed Ace onto an old rope bridge and Ace (being greatly annoyed by his presence) knocked Luffy off the bridge and into the ravine. After learning how lonely Luffy was, Ace warmed up to him, but got annoyed whenever Luffy cried. Ace later grew very protective of him, particularly from Garp, even insulting their grandfather in an attempt to stop his abusive behavior towards Luffy. This protective streak continued into the current storyline. Ace first intervened to protect Luffy from Smoker in Nanohana. Later, when he discovered that Blackbeard meant to kill Luffy and hand him over to the World Government, Ace immediately warned him that he would not let him lay a finger on his little brother. Despite their closeness, Luffy often made Ace angry and frequently worried him by doing reckless things. Another instance would be when Ace was being transported to Marineford. He was however, constantly worrying about Luffy's welfare, repeatedly saying his name and thinking about him.

He is twenty years old and was born on the first of January, he is 185 cm tall, his blood type is "S". Born Gol D. Ace, he was the sworn older brother of Luffy and Sabo, and the biological son of the late King of Pirates, Gol D. Roger, and Portgas D. Rouge. He was adopted by Monkey D. Garp, as requested by Roger himself before his execution. He have slightly tanned skin, a slim build, freckles on his cheeks. His hair is black as well as his eyes. His tattoos are among his most notable features. He have a tattoo on your back with the Barbablanca symbol (purple bones forming a cross behind a purple skull with a white mustache), he have another tattoo on his upper left bicep that reads "ASCE" vertically with the "S" crossed out. He is very intelligent and polite. He likes to eat a lot, parties and suffers from extreme narcolepsy. He has a tendency to never give up a fight. He gets irritated and becomes violent against anyone who insults or harms people close to him. He considers Barbablanca his real father. He often questions whether he should have been born, his father's shadow is too large. He is too stubborn. He ate the Mera Mera fruit, a lodge-type devil fruit that allows the consumer to transform into fire, create it and control it at will.

Though frequently worried by Luffy's extravagant recklessness, inwardly Ace seemed quite proud of his brother's past exploits.

To be honest, he's quite possessive of his little brother Luffy to the point he is labeled to have brother complex.

Ace suffers from a rather extreme narcolepsy. He tended to randomly fall asleep while eating and conversing, leaving strangers around him wondering if he had died.
