Antenna Rick is an alternate version of Rick Sanchez who has two green antennas on his head.
Antenna Rick was one of the few thousand Ricks who banded together to make The Citadel of Ricks. He was a frequent visitor at the Citadel and on one visit he was witness to the trial of Rick C-137 before the Council of Ricks. He was shocked when the Council revealed that The Scientist Formerly Known as Rick was one of the murder victims, like all other Ricks present.
Antenna Rick is a four-armed, long-eared, three-eyed version of Rick. His green antennas clash with the otherwise ash-grey color of his skin. He dresses like most other Ricks and has the same hair color and style.
- It is possible that this is just Alien Rick colored wrong, seing as their only difference is their skin colors.
