Eyebot

The Eyebot is the sixth and fifteenth boss in Heavy Weapon. It appears at the end of the sixth mission and the fifteenth mission as an upgraded version.

Appearance
The Eyebot is a large floating octopus-like robot with 6 floating tentacles, each with a lightning orb on the tip of it. It also has a pink core which looks like an eye, in which it shoots out an energy bullet, and after a few seconds, it closes it, hiding the core so that the player can't attack it.

Difficulty
This one of the first bosses to have a new mechanic in the game, where after shooting a few energy bullets, it then closes it's eye, making the player unable to hit it until it opens again, which makes it very difficult to kill, as the boss will start shooting lighting out of it's orbs. Now when the boss appears from the stage, it opens it's eye that shoot out energy bullets randomly and go through a straight and speedy direction. This attack is the most annoying one as you don't know where the bullets are going to be shot at, and they will directly hit you. After that, it closes it's eye and then one of it's lightning orb's from the tentacles, start to turn pink, and then shoot a lightning bolt, which can easily kill you if you touch it, this attack will be done three times with random lightning orbs doing it. If all of it's lightning orbs are destroyed, it opens it's eye and begins constanly shooting energy bullets until you finally manage to defeat it.

1st Encounter
First, it will start shooting energy orbs from its eye. Then it will start generating lightning bolts from its tentacles (when it shoots lightning bolts, it will close its eye to evade your attack). While doing this, the eye is invulnerable. The lightning strikes are very deadly. The orbs will turn to a purplish hue before generating them. Touching these will result in an instant death.

2nd Encounter
Similar to the first one, but this time, its Energy Cannon shoots faster than usual. It sometimes aims lightning arm towards the player before it discharges in the second encounter.
