Vintage

A team of X-Rank inklings with a light blue ink colour that are referred to as "the supreme rulers of ranked". Their tactic is the X-Fall, in which the four of them stand in an "X" formation and all fire their weapons to take out a group of targets. This leaves an X mark in the ground.

Vintage and Omega also possesses the X-Zone. According to Skull, it is an ability of "total perception" which seems to allow him to predict his opponent's moves. He also seems to move at a very fast pace, but this could just be an exaggeration of the Ballpoint's strafing speed in-game.
Vintage, Omega, Skull, and Aviators were all on the same team (formerly) . However, Skull and Aviators left the team to make a new one.
Vintage seems to have his own ability, the X-Zone. The ability causes the surroundings to change as Vintage then can read the opponent’s movements. It appears that only Vintage and Omega can use the X-Zone, while the other members of X-Blood can not.
He likes extra spicy food.
He formed his team when the X rank was first created by calling out the highest players at the time.
Vintage and Omega are childhood friends.
He invited Double Egg to his favourite restaurant, but the food was too spicy for Double Egg.
In his old team, he wore the White Baseball LS instead of the Takoroka Nylon Vintage.
In Chapter 45, Vintage and Skull were both Agents with Goggles and Gloves in the Hero Mode 2 arc.
Like the rest of X-Blood, a promotional image promoting X Rank depicts him with pure aqua blue ink.
Red Sole and double egg joined later. Omega and Vintage created X-Blood.

Vintage is a pale-skinned, male inkling on X-Blood sporting the 'mush' hairstyle. He has red eyes and his ink color is aqua blue with a red gradient, but can change color at will. His eyebrows are rarely shown, but are notably thin. He wears the Fake Contacts, Takoroka Nylon Vintage, Orca Hi-Tops, and leggings. I mentioned before he's pale but he's REALLY place... but not as pale as Omega, thought.

Vintage has a high opinion of himself and his team, refusing to associate himself with others of lower rank. He is extremely competitive and arrogant as he looks down on the opposing teams and believes that nobody below X rank has any chance of beating him or any chance of becoming an X ranker. He usually has an emotionless and cool-headed demeanor that can change in a second once irritated in the slightest. He is also somewhat spiteful, as shown when he destroyed the wall of Inklings' prayers and wishes to become stronger, and calling anyone who was below S Rank "trash". Hachi described him as seeming empty inside, and Skull explained that when they were on a team together, all Vintage wanted was power at all costs. Even after his defeat against Team Blueperor during the Ranked Battle Cup Final in Chapter 43, Vintage remained serious and prideful but lost his competitive nature, becoming kinder towards his team and showing more emotion. BUT, he doesn't likes teasing.
