Hedlok

Hedlok is a boss character in several modes in ARMS. When fought, it attaches itself to a fighter and uses its six ARMS in total to unleash devastating attacks.

Description
Hedlok was created by ARMS Laboratories as part of their "Wearable Weapons" project, the purpose of which was to create powerful sparring partners for fighters to hone their skills against. It is the follow-up to a prototype armor of sorts that fit over the body, which can still be seen in the background of the DNA Lab stage; however, Dr. C, the overseer of the project, believed that ordinary humans would not be able to effectively control all the ARMS the prototype offered, so Hedlok was constructed instead, with the ability to override the mind of its wearer. Recently, Hedlok has escaped containment and gone on a rampage; though possessing a mind of its own, its objectives are unclear.

Hedlok is a metallic mask with a large mouth lined with yellow teeth, and two ARMS protruding from either side of it. It has no body but clamps onto the heads of other fighters to take control of them. Its glowing red eyes have spiraled irises.

When fighting Hedlok, it will fight with all six of its ARMS (Two sets of three, with each ARM on one side being of the same kind). Because of this, players who attempt to attack it recklessly will wind up having their punch deflected by one of its ARMS and being hit by another, making Hedlok extremely difficult to damage. Rather than unleashing a barrage of attacks with its ARMS, its Rush attack is unique: it fires a large blast from its mouth that barrels forward at high speed before exploding, capable of dealing more than 500 damage if the player is hit by all of it—though, like other Rush attacks, it can be blocked.

Modes
Hedlok appears in three different modes. {{spoiler|

In Grand Prix
Hedlok is the final opponent in the Grand Prix mode after Max Brass from difficulty level 4 upwards. Upon defeating Max Brass, Hedlok descends from above, brainwashing Max and triggering one final fight. Hedlok will have access to Max Brass's signature ARMS and will change them between rounds like other fighters.

The fight against Hedlok takes place in the Sky Arena, like the fight against Max Brass before it. It is different from previous fights in that it has no timer—each Round will continue until either the player or Hedlok is KO'd.

Upon defeating Hedlok, it is suddenly launched off of Max Brass's body. Max appears dazed for a moment afterward but is otherwise unharmed, and flexes his muscles before the Awards Ceremony begins.

In 1-on-100
Hedlok is the final opponent that must be fought in 1-on-100, attaching itself to one of The Cell. If the player is not at full health, a thermos of HP Juice will be dropped in for them to heal shortly before Hedlok's appearance. Hedlok's ARMS will always be the first signature ARM of the fighter the player is using. }}

In VS Hedlok
Hedlok is the namesake of the VS Hedlok mode, seen in Party Match, being the primary opponent players must fight against in it (up to three Fighters can take part). It can use any combination of fighter and ARMS. In order to win, it must be defeated before the timer runs out, even if it has less health than the players fighting it. It is affected by items just like normal fighters, allowing it to be damaged or healed, and it can use a special. The difficulty of the fight is linked to either difficulty level 4, 5, 6, or 7 from Grand Prix, as indicated next to its name.

Trivia

 * Although Hedlok was officially revealed as part of the ARMS Global Testpunch on 2017-06-02, it was leaked before its official reveal on a Twitch.tv stream.
 * Barq is not present when Hedlok attaches to Byte.
 * Hedlok’s name is likely a reference to a headlock, which is when a person’s arm is wrapped around another person’s neck, thus trapping them.
 * Hedlok has two separate sets of victory poses—one used in Grand Prix mode where it stays attached to Max Brass and laughs triumphantly, and one used in 1-on-100 and VS Hedlok where it detaches from the fighter it was using and flies towards the screen.
