Ancestor Rabbid (later renamed Lapinibernatus in Season 3) is a ancestor of the Rabbids with a deeper voice and a slightly different language that first appears as the deuterogamist of the episode Jurassic Rabbid. And then as the main protagonist of Rabbid 2.0
Unlike his modern relatives, Ancestor Rabbid possesses genius level intelligence and common sense that modern Rabbids' lack. His intelligence allows him to build a variety of inventions from a Time traveling washing machine, a time traveling television, and a bubble device. He is also shown to be a talented chess player, as he was able to beat John Charles in "Rabbid Theory".
Like Gina Xenson and John Charles, he can get frustrated by other Rabbid's stupidity, though at times he is able to get along with his fellow Rabbids. He can also be annoyed by the other Rabbids' tendency to cause trouble due to their stupidity, such as them (and/or their antics) getting in the way of him fixing his time machines.
Season 1 Edit
He was discovered frozen by two men. The rabbids unfroze him and he revealed that their race was once smart (and had hair), but due to the ice age their brains got smaller but they got taller. He invents a few machines and wants to impress his modern day relatives, but is frustrated by their stupidity. At the end, he builds a Time washing machine and goes through time.
In Rabbid 2.0, the present day rabbids steal a important part of his time machine and he tries to get it back. He finally manages to get it and then saves the present rabbids from Bob The Dog (who was angry at them because they harmed him). At the end, the rabbids pronounce him a hero and get him in the time machine, he fixes it and goes away.
Season 3 Edit
He returns in Season 3.
He is first seen in Rabbid on Film, where he is the director of the Rabbids blockbuster movie. Also, it seems he is working on a new invention, later revealed to be a TV Time Machine (due to the rabbids destroying his Time Washing Machine).
In Bubble-Wrap Rabbid, he creates a bubble device to keep the rabbids away so they don't bother him, but things go haywire.
In Rabbid Theory, he proves to John's boss that he is indeed smarter than the others and even manages to defeat John himself. Earning him a new rank in science.
In Rabbid Real Estate Rampage, he is one the rabbids to be captured by the builder who wants to build a house on the Rabbids' junkyard.
In Checkpoint Rabbid, in order to work on his time machine, Lapinibernatus sets up a checkpoint to keep the other Rabbids at bay.
In Rabbid Mate, Lapinibernatus and a group of Rabbids battle over control of a Rabbidroid.
