History
B3-NK1 appears in EP023, 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.

B3-NK1 makes a cameo in EP035 as a member of Baddinyan's pirate crew for Directator's latest movie.

Trivia

 * 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.

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

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.

 * "B3-NK1" is the name "Benkei" partially cyphered to resemble a machine's serial number.
