Crocotoxes

The Crocotoxes were breed of toxic eel monsters (one red, one blue) used by Darkonda. He and his partner were sent to Earth to spread its toxins by Darkonda. One of them could swim through space and swim through Earth water, while the other hit the rangers with a green energy barrier that became a net around them. Darkonda had eggs to hatch into an army of Crocotoxes. Zhane destroyed the red one with his Super Silverizer while the other was destroyed by the Astro Delta Megazord.
