Tigris was the son of Hethrir and Rillao.

Biography
When Tigris was conceived, the Sith Lord Darth Vader had high hopes for turning him to the dark side. Rillao, however, had other ideas, and spirited herself and Tigris (who had no Force powers anyway) away. Hethrir eventually caught up with them and tortured Rillao, keeping Tigris as his servant.

Hethrir - whom had become the Procurator of Justice - fled to his own homemade planet, a Worldcraft, with his followers including Tigris. Hethrir sought to become the new Emperor in his Empire Reborn movement; to do this, he had to consult Waru, a hideous, extradimentional, Force-sensitive mass of flesh that claimed to be a healer (though he really robbed his victims of their life force to try to create a portal back to his own dimension) and resided on Crseih Station.

Though relegated to the lowly position of a nursemaid, he still remained loyal to Hethrir serving him as well as he could. He was also taught by Hethrir that his mother Rillao was a traitor who stole any Force potential Tigris may have had. Unlike, Hethrir's other followers including the Helpers and Proctors, he was kinder in the treatment of the children held captive on the Worldcraft. Tigris was also small for his age due to malnutrition.

In 14 ABY, at about the age of twelve or thirteen, Hethrir kidnapped the children of the New Republic Chief of State Leia Organa Solo and Han Solo. While, the Solo twins Jacen and Jaina were placed into groups with other kids and put under the control of older children known as Proctors, their younger sibling Anakin was to be sacrificed to Waru in exchange for helping Hethrir.

During this time, Tigris was placed in charged of Anakin. Thus, he developed a relationship with the then-three year old boy. When, Hethrir left for Crseih Station to sacrifice Anakin to Waru, Tigris accompanied his master. Later, at a park on Crseih Station, he and Hethrir encountered C-3PO, who attempted to retrieve Anakin. However, the droid was stopped by Hethrir who disabled the droid.

Later, Hethrir was about to sacrifice Anakin to Waru. However, he was stopped by the arrival of Leia, Han, Jedi Master Luke Skywalker and Rillao, who had befriended Leia. In the end, Waru pulled Hethrir back into his energy field, having given up all hope of ever creating the portal to return to his galaxy, thus destroying them both. Mother and son were soon reunited and they decided to reacquaint themselves with each other. The whereabouts of Tigris and Rillao afterward are unknown, though it's possible they relocated to Belderone with the rest of the Firrerreo refugees.
