B3-NK1 (Japanese: からくりベンケイ Karakuri Benkei) is a Rank B Lightning-attribute Yo-kai of the Brave tribe.


B3-NK1 wears a yellow armor with purple shoulder-neck and waist pads, a number of blue beads and black gloves with gold linings. He has green facial features. He also carries a naginata.

In the anime, he is eager and hard-working in his quest for the "Hero's Screw", which he believes he could awake the true power of his naginata.

Using his naginata, B3-NK1 can pierce through modern technology devices without making holes in them, and uses it for looking for screws needed for said devices to work in order to assimilate them with his weapon and forging the "ultimate weapon". In particular, he looks for Heroic Screws (Japanese: 英雄のネジ Eiyū no Neji), special screws that represent the souls and powers any form of machinery, and it's said that collecting 1,000 of them will awaken the true power of his naginata.


Yo-kai Watch animation series

B3-NK1 appears in Yo-kai B3-NK1, in which he causes some of the electronic artifacts in the Adams House to suddenly stop working. When confronted by Nate, he reveals he caused these malfunctions in his search for the "Hero's Screw", which he states that they can awaken the true power of his naginata, collecting his 998th from Nate's air conditioner, and the 999th from the vacuum cleaner near Jibanyan, Nate, and Whisper. To fix B3-NK1's messes, Nate summons Robonyan, who is then attacked by B3-NK1's polearm when the Yo-kai notes Robonyan's metallic body. However, Robonyan oddly turns out to enjoy its piercing, to the point where he kept prodding B3-NK1 to keep searching him for a Hero's Screw despite his denials to the group when confronted on it. Suddenly, Robonyan begins extending his limbs, tails, and neck, then quickly retracts them, and falls off of B3-NK1, leaving behind a Hero's Screw, and one of the best in the collection to boot, and assimilates it with his polearm, causing it to assume a brand new form. B3-NK1, out of gratitude, gives Nate his Yo-kai Medal.

In The New Yo-kai Watch, B3-NK1 was seen in Yo-kai-lifornia where he is among the Yo-kai waiting in line for the Yo-kai Watch Model Zero to go on sale.

B3-NK1 makes a cameo in Titanics Of The Caribbean as a member of Baddinyan's pirate crew for Directator's latest movie.

"Karakuri Benkei" translates as "mechanical Benkei". "B3-NK1" is the name "Benkei" partially cyphered to resemble a machine's serial number.


B3-NK1, like Benkei, B3-NK1 is based on the warrior monk-turned-lieutenant who served Minamoto no Yoshitsune (see Benkei#Origin).

His Japanese name, "Karakuri Benkei", refers to karakuri ningyo, mechanized puppets built during the years from the 17th to the 19th century for entertainment purposes, festivals and stage tricks.


  • Even after B3-NK1 has awakened the new form of his polearm in EP023, in his subsequent apperances, the polearm seems to have returned to normal.
