Emiya Shirou.

Because he's Shirou, it is a logical conclusion that he's an excellent cook.

Emiya Shirou; originating from a path that fits none of the routes. A year after the Holy Grail War, Ilya died--not a good start. Then, as he spent a lifetime chasing his ideal, trying to save people, he found himself alone. That was fine, all he cared for was saving people. Finally, he made a contract with the world itself: in exchange for power now, he would serve it after death, saving humanity, and thus enabling him to save people he otherwise couldn't in his present.

Then he got betrayed and executed by one of the very people he'd saved, blamed for starting a war he'd in fact finished. But Emiya Shirou didn't care; he'd followed his ideal to the end and had no regrets. Then... he became a Counter Guardian: summoned only when something that would wipe out humanity happened, forced to kill the perpetrator and leave. An uncountable time outside time, summoned with no reference to causality but only seeing that which he hated and forced to do the opposite of his life's work.

Thus, when he was summoned into the 'present' as the Servant Archer, he was left focused on one option: kill Emiya Shirou himself, and hope that the paradox freed him from his torture. Rather a lot of work went into this, but in the end he was unable to make his past self concede, and was thoroughly killed. He did, however, reconcile himself with his ideal once again.

*Name: Sakuya Izayoi
*Universe: Touhou Project
*Appearance:
*Personality: Sakuya is rather refined and elegant. However, she always shows traces of being somewhat ironic. She has another personality, where she leaves her servant elegance to her assassin skills, represented when her eyes change from blue to red.
*Powers/Skills: Sakuya excels at throwing knives. She has the strange ability to briefly control time, by either manipulating it to fake illusionism or by stopping it.
*Brief Bio: Sakuya was on usual duty, cleaning and serving her mistress Remilia Scarlet at the Scarlet Devil Mansion. However, she showed more and more worriness to the world around her, somehow. Through her power, she was able to feel some distortions, both in time and space. In a certain day, while she was cleaning some of the bookshelves at Voile, the magic library of Patchouli Knowledge, she noticed that the library assistant, Koakuma, was gone and nowhere to be seen. She kept her usual business, until she was able to find a distortion, in which she was sucked.
*Equipment: She carries only her knives in a pocket hidden in her left leg.
*Others: Her theme will be The Maid and the Pocket Watch of Blood (dBu remix).

*Name: Alice Margatroid
*Universe: Touhou Project
*Appearance:
*Personality: Alice is really ironic and hardly express her true feelings to others. She shows a hint of loneliness sometimes.
*Powers/Skills: Alice is good at manipulating magical crafted dolls that she uses as her weapons. Each of the dolls has a way to attack.
*Brief Bio: In her research in order to learn how to create a living doll, Alice suddenly finds a strange, black puppet lying in a tree near her house. She became curious. After all, it was easy to get lost into the Forest of Magic. She kept it inside her house. In one certain night, the doll started to shine and release a black aura around Alice. She tried to control it, but that made her get sucked by a eerie energy.
*Equipment: All that she possess is her dolls and her grimoire.
*Others: Her theme will be the Grimoire of Alice (dBu remix).

*Name: Pablo. He introduces himself as the Judge without exception, for reasons not openly stated.

*Universe: OFF

*Appearance: A pure white cat with a large head, surreal grin and rather stiff hind legs.
Concept art here, in-game sprite art here, descriptive fanart here.

*Personality: Polite and dignified. The Judge is a knowledgeable, discerning individual who gladly interacts with others with a touch of wit and drama. Although the Judge is quite wordy, his attitude is not condescending, and treats others as equals. That said, the Judge can be authoritative when the situation requires it. The Judge is honest in what he says to or concerning himself or others, although not typically open about his own origins. Notably, Pablo is still grieving over the death of his brother and regrets the part he played in the destruction of his home universe, and his fear of repeating past mistakes may influence his decisions.

*Powers/Skills: The Judge can exert a psychic influence on an opponent's body. This induces brief surges of disabilities such as paralysis and blindness, or more direct damage by rupturing blood vessels to cause internal bleeding.
The Judge's own body is that of an arthritic cat, not capable of significant harm. On paper, anyway. We all know how much damage a household cat can do in practice.
Within the single warehouse of his own Zone 0, the Judge has been seen teleporting and may have possessed powers similar to the Guardians of other Zones, but these are localised to a building far away, granted by a being long dead.

*Brief Bio: The Judge is a cat who lived in a warehouse in a world of four surreal areas named Zones. An entity called the Batter turned up at the warehouse claiming to be a messiah, and the Judge taught him some skills before sending him on his way. The Batter first entered Zone 1, where he began his self-appointed task of destroying the spectres harassing the humanoid Elsen living there. After encountering Dedan, Guardian of Zone 1, the Batter observed him exploiting the Elsen's fear and paranoia, and eventually killed him. The death of Dedan led to Zone 1 collapsing into a colourless, lifeless world, and the Batter continued to Zone 2.

The entity claiming to be Zone 2's Guardian was identified by the wandering Judge as Valerie, his feline brother. Valerie acted strangely and violently towards the Elsen, causing the Judge considerable confusion and distress. During a showdown, the true Guardian of Zone 2, a massive phoenix-like creature named Japhet, emerged from Valerie's body where he'd been hiding, killing him. The Batter slew Japhet in turn, and Zone 2 followed the same path as Zone 1. The Judge was deeply shocked by this, and remained in Zone 2 for some time, grieving.

Meanwhile, the Batter continued to kill the Guardian of Zone 3 before entering a space called the Room, where the Queen of the Zones resided. The Batter killed both her and a mysterious child whose death had the same nullifying effect on the Room itself. Following this murder, the Judge finally reappeared to confront the Batter, condemning his rampage and regretting that he had allowed it to take place. In one ending of the game, the Batter killed Pablo, then extinguished the light illuminating the empty Zones forever. In the other, the Judge overcame the Batter, killing him at the price of spending the rest of his days in a bleached, empty world.

Until that world collided with Crossover City.

*Equipment: Bad memories and a considerable vocabulary.

*Others: As a point of interest, he is known to have owned a basement full of narcotic sugar, possibly intended for personal use. Like everything else in OFF, though, there are unspoken shenanigans involved.
His final duel with the Batter is accompanied with this theme regardless of perspective. His first, peaceful encounters in Zone 0 are accompanied by this tune.
