A faucet-style Perfect Chojin.


The character's name "Jak Chi" is a pun based on the Japanese word for 'faucet' (jaguchi).[1] [2] The romaji and katakana for his name both call him 'Jak Chi', although 'Jack Tea' appears a popular alternative within the fandom. 


Jak Chi first appears during the Perfect Origin Arc. [3]

He arrives as part of the second group of the Perfect Chojin, where Nemesis speaks as their leader. [4] Jak Chi taunts Geronimo that he shall die, if he enters a ring with all the Perfect Chojin now gathered in one place, but Geronimo blows them away with his Apache War Cry. [5] Jak Chi retaliates with a Boiling Shot, before Marvellous and the others continue the attack. [6]

Jak Chi then goes to a seven-stepped pyramid to begin a new tournament against the Seigi Chojin and Akuma Chojin. [7] Jak Chi is assigned to fight Black Hole. [8] He hovers in the air above the ring-post, with steam that emits from his feet, and uses Boiling Shot upon Black Hole, who howls in pain, but - using the shadow of the Boiling Shot - Black Hole manages to escape. Black Hole gains the advantage with a Front Suplex. He later avoids another Boiling Shot by expanding the hole upon his head. [8]

Black Hole lands a Body Press on Jak Chi, but a second attempt at a Front Suplex is countered by Jak Chi's use of a Boiling Shot that reverses the direction of the suplex. [8] Jak Chi tries another Boiling Shot, but Black Hole escapes with a Shadow Hiding technique. [9] Jak Chi aims his Boiling Shot at the shadows,which causes damage to Black Hole, until Black Hole splits into multiple shadows. Eight versions of Black Hole appear, but Jak Chi uses Boiling Shot to attack all eight shadows. [9]

Jak Tea then uses Eye Dowsing. This forces the shadows to disappear until only the real Black Hole remains, and - when Jak Chi uses another Boiling Shot - Black Hole counters with a Glory Hole. Black Hole then uses a Canadian Back-Breaker and a Reverse Deadly Drive, but Jak Chi counters with a Double Boiling Shot, a Kick Fireball and Drill Dowsing. He Jak Tea finds an underground spring with the final technique, which causes a burst of water to shoot upward. The steam blocks out all sunlight, leaving Black Hole unable to uses shadows to escape. [9]

Jak Chi gains the advantage with a series of blows and techniques. [10] He taunts Black Hole with a hint of shadow from his Coolant Shot, but he makes the shadow disappear at the last moment and uses a Faucet Crusher. Black Hole retaliates with poking him in the eyes and kicking him in the groin, and support from Buffaloman and Springman motivate him by offering support. He uses Extreme Black Hole to suck in everything in sight. [10] Black Hole is incapacitated, but the match cannot end as his hand is still moving. [11]

It is revealed that even light itself was pulled into Black Hole's Extreme Black Hole, and this leads to him communicating psychically with Pentagon. He then uses a Fourth Dimension Cross, which causes him to turn into Pentagon. [11] Pentagon attacks Jak Chi with Angel Wing Claws, which burns Jak Tea's flesh about hs face. [12] Pentagon attacks with a series of blows, ending with Space Shuttle and Space Falcon, and Jak Chi tries to retaliate again with a Faucet Crusher, but Pentagon stops it with a Chronos Change. This allows Jak Chi to take monumental damage. Pentagon then swaps places again with Black Hole. [12]

This defeats Jak Chi. [12]

Jak Chi then commits suicide by standing on the geyser. [12]
