Hedlok

Hedlok is a boss character in several modes in ARMS. Notably, it has six ARMS (two different types, with three copies of each) when fought, being the only character in-universe to have such a distinction.

Description
Hedlok resembles a metallic mask with a large mouth, having four ARMS, two on either side of it. Its body appears to change into the form of a random fighter, gaining their abilities and control of the fighter's two extendable ARMS in the process. Hedlok also notably has spiraled irises.

Hedlok was created by ARMS Laboratories as a follow-up to Helix. However, it broke free and went on a rampage. Hedlok inflicts brainwashing, and its motivation seems to be wanting to destroy everything in order to "grow".

In VS Hedlok
Hedlok is the namesake of the VS Hedlok mode and the primary opponent players must fight against in it. It can use any combination of fighter and ARMS. In order to win, it must be defeated before the 99-second timer runs out. It is affected by items just like normal fighters, allowing it to be damaged or healed. {{spoiler|

In 1-on-100
Hedlok is the final opponent that must be fought in 1-on-100 mode. It takes the form of a standard 1-on-100 enemy. }}
