Ventrilosquid's Species

Ventrilosquid's Species is an unnamed race of telepathic (possibly) squid-like aliens.

Appearance
It is unknown what this species looks like but given the wordplay of Ventrilosquid's name, it is possible they resemble squids.

Powers
This species is "sort of" capable of telepathy.

This species has ventriloquism powers, meaning they can control other beings like puppets.

Omnitrix Transformation
The Omnitrix's representative for this species is named Ventrilosquid. Despite having never appeared on-screen, it is confirmed that he was first used prior to the Omniverse episode "Let's Do the Time War Again".
