Cretaphid v4

This is the third form of the Cretaphid. It shoots deadlier Precision Chemical Lasers, Heat-Seeking Plasma, and it roams around the room to try to hit Samus. When the dots are red, they cannot be destroyed unless they turn blue. When all of the dots are destroyed, you can shoot its face. Repeat this until this Cretaphid's destroyed. You will see energy all over the room and an Octolith from the battle.

Logbook Entry
"The apex of the CRETAPHID line of cybernetic defenses, this ultimate model deploys lethal lasers and homing plasma from a mobile tower whose very casing is an offensive weapon. A key component of ALIMBIC military technology, it was designed to safeguard the ALIMBIC's most sacred objects."
