Tygra is the son of Javan, the sole surviving heir of the fallen Tiger Clan. He was adopted by the Thunderian royals and became a prince when he was a baby; currently, he's the elder adoptive brother to Prince Lion-O and adoptive son to King Claudus. After surviving the fall of Thundera, he and the surviving cats formed the new ThunderCats and serves as second-in-command. Should Lion-O ever fall or relinquish his title as King, Tygra is next in succession as Lord of the ThunderCats.
