Mindflayers are floating, humanoid machines with teal, feminine bodies and robotic heads. The machine itself is integrated into the head and upper body, having a blocky "head" with two shoulder segments and a pair of rectangular protrusions that jut from its back. Lines along the metal glow with teal light, and five tentacle-like cables extend from different points, ending in glowing stingers that leave behind trails of teal light. (taken from wiki)

In this video, Mindflayers are classy, egotistical, rude & mocking machines. They will mock and tease V1 from afar with witty comments. Mindflayers also have a tendency to get upset very fast.
