Deathtanz Mantisk (デスタンツ・マンティスク Desutantsu Mantisuku) is one of the first four bosses of Mega Man Zero 3. Mantisk is based on a praying mantis and the grim reaper, and was originally created for the sole purpose of execution, using his "Grim Reaper Scythes" to dispose of Reploids. In the Remastered Tracks Rockman Zero Telos, Deathtanz says he doesn't like to take an unnecessary life and that the dullness of his scythes were proof of peace. However, after he was modified by Dr. Weil, he cares for nothing besides killing. He also has a habit of using the Japanese onomatopoeia, "chikachika", when irritated. He was sent by Dr. Weil to capture the Baby Elves, and was defeated by Zero. Mantisk, at least in his modified form, also seems to have a fear of dying, as evidenced by his last words to Zero after being defeated in his rematch in Weil's Laboratory.

An image of Deathtanz appears in Mega Man Zero 4 as one of Dr. Weil's first form attacks, launching one of his scythes at Zero.


Mantisk mainly attacks with his scythes either throwing them as boomerangs, slashing from above, doing a quick stab, or throwing them across the floor, up the wall and then back to him. If the player has A or S rank, he will use his EX Skill Rock Breaker. One strategy to defeat him is to equip a normal body chip and attack him with a charged Recoil Rod, which will knock him back and sometimes interrupt his attacks.

Defeating him will give Zero the Light Body Chip, and if the player is at A or S rank, the 1000 Slash ability.

  • "Chikachika" (ちかちか) is a onomatopoeic term commonly used in Japanese comics and graphic novels to describe or indicate the twitching/flickering of ones eyes. Apparently Mantisk has made a habit of saying this every time something annoys him enough to make his eye twitch.[1]
  • Deathtanz was misnamed as "Deastants Mantisk" in the English instruction manual of Mega Man Zero 3.
  • Deathtanz Mantisk appears in Mega Man ZX as a secret boss in Area N, in a door that only opens if a Mega Man Zero 3 cartridge is inserted in the Nintendo DS.
