Octodiver

The Octodiver is a variant of the Octotrooper and the Twintacle Octotrooper.

Description
Unlike their regular counterparts, Octodivers are equipped with snorkel masks and hide in pockets of Octarian ink. When Agent 3 approaches them, they will quickly surface from the ink and begin firing. They are able to dive into their own ink when under attack or too far away from their target as a means of defense.
