Martian Series (HGD)/Seabed 6/Purple Boss Vampire Eel

About
The Purple Boss Vampire Eel flies amongst the Yellow Vampire Eels in the boss area. Its attack is to shoot an accelerating purple laser beam which deals poison damage. As the laser attack pierces, it is possible for characters to be damaged multiple times by the attack, making for some severe damage taken. Despite possessing a poison-type attack, this boss does not have a resistance to poison.
