The Cell

A 1-on-100 enemy is a creature from ARMS. They appear in 1-on-100 mode in waves of 9 or 10. The goal of the fighter is to take out one hundred of them. They also appear in Training, holding up targets and allowing fighters to practice their punches by taking them out. These enemies are incredibly weak; having no health bar, they can be eliminated not only with a single attack, but also by having another fighter thrown into them.

Description
1-on-100 enemies resemble Helix, but are gray instead of green and have a much larger mask with one eye instead of Helix's small visor with two and also do not have his "hair". Despite these differences, they are identical to Helix in abilities and are therefore able to stretch their bodies just like he is to dodge attacks. According to a loading screen message for the game mode, the enemies are prototypes of Helix, which would explain their similar appearance and abilities.
