HE DIED!!!!!!! Why the author had to kill him?!?! OMG!!!!! T_T

Something about Ace:

Portgas D. Ace (born Gol D. Ace) was the adopted older brother of Monkey D. Luffy and son of the late Pirate King, Gol D. Roger and his lover, Portgas D. Rouge. He was adopted by Garp by request of Gol D. Roger before his birth. He was the Second Division Commander of the Whitebeard Pirates and onetime captain of the Spade Pirates before his untimely death

Ace wore an open-front shirt until he received Whitebeard's tattoo - afterwards, he stopped wearing anything over his upper body (except when on winter islands). He wore black boots, black knee-length shorts with an eyelet-studded orange belt, and a blue pouch belted around his left leg. He also wore a short second belt with a large "A" on the buckle over his right hip, but leaves it unbuckled and lets the free end hang from the back. A dagger in a green sheath hung at his left hip. On his left arm, he wore a Log Pose and a red and white striped bracelet around his wrist, an orange elbow guard, and his "ASCE" tattoo. He wore a red beaded necklace and an orange hat with two blue smileys, one frowning and one smiling, and a string of red beads sitting above the rim. Two long orange side straps hung down from the hat and meet at a large medallion of a bull's skull with orange tassels hanging down from it

Ace and his brother, Luffy, were very close. As a child, Ace was protective of Luffy particularly from Garp, even insulting Garp in an attempt to stop Garp's abusive behavior towards Luffy. This protective streak continued in the current storyline. Ace first intervened to protect Luffy from Smoker in Nanohana. Later, when Ace discovered that Blackbeard meant to kill Luffy and hand him over the government, he immediately warned him that he wouldn't let him lay a finger on his little brother. Apparently, Ace had been known to frequently share stories about Luffy with the other ranks of the Whitebeard Pirates (including the Shichibukai, Jinbei). He was quite overjoyed when he learned that Luffy gained his first bounty and wasted no time showing the wanted poster to Whitebeard himself. Despite their closeness, Luffy often made Ace angry and frequently worries him by doing something reckless. Even near his death, Ace grew angry with Luffy's reckless infiltration of Impel Down.

Ace tended to portray a typical good-big-brother behavior, such as asking the crew to keep an eye on his little brother. He also ensured Luffy had a way of meeting up with him by giving him a Biblicard. They respected each other's choices despite how different they are and understand that the other is very strong, so they can usually take care of themselves. Luffy believed that if he grew worried about Ace and rushed to help, Ace's ego wouldn't allow it, so he initially left him alone even after discovering that Ace was hurt via the Biblicard. However, when he learned that Ace had been captured and was due for execution and saw that Ace's Biblicard had burnt down to a tenth of its original size, Luffy regretfully decided take a side trip and save Ace instead of sailing directly from Amazon Lily to the Sabaody Archipelago to reunite with his nakama.

It was revealed at Ace's execution that Ace actually is Gol D. Roger's son, not Monkey D. Dragon's as previously assumed, and that he was taken in by Garp. This makes Ace and Luffy brothers only through adoption, but brothers nonetheless. A flashback shows Luffy and Ace first meeting as young children, which means that Luffy is aware of this fact. It also shows Luffy having his trademark strawhat and scar under the eye, indicating that Ace first met Luffy after Shanks left Luffy's home island. A later flashback shows them officially declaring one another as their brother by drinking sake from each other's cup. In a conversation with Iva, Luffy reveals he is also aware that Ace's father is Gol D. Roger.
