From Jikuu Senshi Spielban.

The Battle-Lifeforms are Dr. Bio's monsters created out of organic material. Only a few were produced and at the end of the series Bio would operate on himself and become a Bio Lifeform.

Sporeja: The first of three Bio Lifeforms. Sporeja could metamorph itself into green slime for infiltration as well as morph into a flat starfish-like mass to wrap itself around its victims in order to consume them. After eating a human Sporeja could assume their identity. Sporeja was used to break into a museum and after eating and impersonating a guard, a diamond was stolen which Pandora used as an offering to the Waller deity. Dr. Bio later upgraded Sporeja with the ability to shoot deadly gas. Spielban was almost eaten, but he finally killed Sporeja with his lance.

Cottonja: A floating spore-like organism that emerged from a rose. While conducting his research by the lake Spielban found a sad little girl. She quickly ran off leaving her backpack behind. The backpack had her address and name which revealed that she was the daughter of a renowned scientist. Spielban returned the backpack, but the scientist and his daughter were being held hostage by the Waller. The scientist was forced to conduct experiments for the Waller while his daughter kept him fed and made it appear to the public that everything was alright. Spielban sneaked in to save them, but Deathzero threatened to kill them and forced Spielban to throw down his gun. The scientist mustered his courage and broke free from the Kinclons clutches which allowed Spielban to attack. Cottonja had no body and it was difficult for Spielban to land a decent hit. Spielban destroyed it with his laser sword finishing attack.

Seaja : An octopus-based monster and Dr. Bio's final lifeform. Seaja was covered in tentacled limbs and was colored bluish grey. Seaja was unleashed into the ocean where it would spawn from its arms. Dr. Bio's plan was to infect all the Earthlings with small aquatic parasites causing the infected person enter the ocean where they would turn into fish people. Spielban went scuba diving and confronted Seaja. He told Diana what was going on and she volunteered herself as bait to lure Seaja out of the water. Meanwhile, Spielban stumbled into Bio's hidden mountain lab and demolished it with his land vehicle. Diana, meanwhile, was engaged in battle with Seaja, who could spit out a sludge-like material from the large opening on its face and Diana was hit by it. Spielban managed to join in the battle and kill the monster. After Seaja was destroyed, the victims of the parasites were freed of their manic need for the ocean.

I also did Dr. Bio's monster form Bioroid-Bio , a small octopus-like mutant that Spielban fought before he took on Cottonja and Emperor Guillotine's snake-like hand .
