The Polarizoa (coming from the word Polarizer and Hydrozoa (a genus of jellyfish)) is a enormous, pressure-adapted jellyfish-like creature that is capable of delivering extremely high electrical shocks via the use of the two tentacles dangling from it's lower body. It's made out of a strange, extremely soft oily substance, covered with a thin layer of extremely-fast-regenerating gel which helps it keep it's shape.It's organs are slightly more solid and are capable of regenerating extremely, extremely quick.
The Polarizoa is very, very soft, Railgun shells and Harpoon shots will pass straight through it. The player can even dive through it, but it's center is filled with a extremely acidic substance which will quickly deplete the player's health and kill him or her, diving through or tearing holes in the Polarizoa will leak some of this acid, but it'll quickly dissolve.
The Polarizoa delivers electrical shocks via a large organ in it's center, shaped like a tower, this organ generates electricity, which is delivered to it's two tentacles, where the small tendril-like protusions on the end of the tentacles transmit the current to it's target. In the top of this large organ is the only vulnerable part of the Polarizoa, it's brain, which is the only hard, solid part of it. (Which, while still invulnerable to railgun shots, is vulnerable to harpoon shots/melees)
It's known for treating Submarines as prey, attempting to adhere it's tentacles to the submarine and overloading it with electricity, generating power failures and overloading the reactor (also charging batteries extremely quick and making lamps explode/get really bright) until the ship runs out of air/makes the reactor explode, also causing slight, very slow damage to the hull near the tentacles. A player inside the ship won't get shocked by touching surfaces where the electricity is being spread throughout the submarine.
Polarizoas are only dangerous if either the end of the electric tentacles or the center of the head full of acid are touched, touching any other part will not damage the player at all, and the Polarizoa does not actively move it's tentacles to attack the player, as it has no eyes and cannot detect him or her.
The way to stop a Polarizoa is to either:
A. Cut one of it's tentacles so it cannot complete a circuit with the ship and it stops delivering electricity to it.
B. Destroy the organ in it's center.
c. Explode it to pieces. (Not with railgun)
If any of the tentacles in the Polarizoa are cut, they will regenerate after a while, and it'll go back to overloading the ship with electricity. Destroying the electricity-generating part will also stop it temporarily (a bit longer), but it'll leak acid which may damage the ship/player, and it'll regenerate after a while. Destroying the brain will kill the creature (with acid still leaking, but only in a small area). The acid in the Polarizoa is very, very corrosive, being able to damage the ship greatly, but only in a small area, the acid, once depleted, will be slowly generated again.
There are several small organisms called Hydrozers (Coming from the word Hydrozoa and Polarizer), which are symbiotic aquatic organisms that depend on the Polarizoa, travelling with it and resting inside the outer layer of it.
Hydrozers are a bit fast, and deliver nasty stings (like a jellyfish) to anything that may have attacked the Polarizer, in a effort to protect it. They're easily dispatched with any weapon, and they deliver very low damage per sting. A single Polarizoa can contain anywhere from 7 to 20 Hydrozers. And Polarizoas come in pairs, sometimes.
So, to put it shortly:
- The Polarizoa is a boss which will attempt to put its tentacles anywhere on the ship. If it does so, then it'll generate electricity overloads, which may damage the reactor and make equipment act erratically (doors closing and opening at random would be neat) and will damage the hull slightly.
- It's hitbox is very small, only composing of the small brain organ in the center of it's acid-filled interior. It's invulnerable to Railgun shots (but hitting it with the railgun will still make it leak acid everywhere and trigger the hydrozers to attack). The brain is vulnerable to harpoon and melee attacks.
- The only damaging parts of the Polarizoa are the end of the tentacles, and it's center.
- Attacking the Polarizoa will make it spawn Hydrozers.
- Hydrozers inflict low damage and are very fragile.
- Maybe a Polarizoa can be used as a second-hand reactor, if managed carefully and fixing any parts of the hull that get damaged due to the heat generated by the electricity.
How to kill/stop a Polarizoa:
1. Grab a diving suit and a weapon
2. Dive outside of the ship and get close to the Polarizoa
3. Hit the small organ in the center/cut the tentacles
4. Escape from the/Kill the Hydrozer swarm.
5. Go back into the ship.
6. Repair your stuff.
7. Get to the goal.
TL;DR: A boss which cannot be killed directly and damages the ship with electricity, and spawns minions.
