Knuckle Joe (ナックルジョー Nakkuru Jō) is an enemy and minor character from the Kirby universe but he is a major character from Kirby's TV series. He originally appeared in Kirby Super Star (Kirby's Fun Pak in PAL regions), the first game in the Kirby series to utilize the Helper functionality. This allowed Kirby to create a Helper ally from his current power to assist him throughout the level. Knuckle Joe is the result of combining the Helper function with the Fighter ability. His attacks are inspired by Kirby's own when using this ability.
In SSBB, Knuckle Joe is one of the supporting characters that spawns from the Assist Trophy item. When Knuckle Joe is summoned, he uses his "Vulcan Jab" technique, which is a series of rapid punches, on the nearest foe. Afterwards, he finishes the opponent off with one of two "finisher" attacks: the strong, short-ranged "Smash Punch", or the electricity-charged uppercut known as the "Rising Break" technique. The finisher he uses is chosen at random. He could be considered the most powerful Assist Trophy character, because if he manages to trap an opponent in his initial barrage, he can KO them from 0%.
A martial artist known for amazing attacks like the Vulcan Jab. With his bandana, he looks and fights the part of a Muay Thai boxer. When Kirby copies Knuckle Joe, he gains the fighting techniques of a hand-to-hand-combat expert. Knuckle Joe also engages in friendly block-breaking competitions with Kirby. His other famous techniques are the Smash Punch and Rising Break.

Via the hacking program BrawlBox, hackers have succeeded in replacing the model for the Yellow Alloy with Knuckle Joe's model. Additional hacks have smoothed out Knuckle Joe's motions and given him some original animations. However, like the Alloy he is replacing, he cannot use special moves or grab ledges.
Knuckle Joe returns as an assist trophy in Smash Bros for 3DS and Wii U. He uses the same attacks he did in Brawl.
A martial-arts master, Knuckle Joe can be inhaled by Kirby and his Fighter ability copied. If you summon him, he'll leap toward the enemy nearest you and unleash his powerful Vulcan Jab attack. He'll then finish off his target with a devastating Smash Punch or Rising Break.
Knuckle Joe returns once again as an assist trophy in Super Smash Bros. Ultimate. He still uses the same attacks he did in Brawl.
