A staunch, level-headed warrior, based on the tiger, Tygra is the one Lion-O often turns to as second-in-command and for counsel. He is responsible for the design of all of the ThunderCat structures on Third Earth — the Cat’s Lair and the Tower of Omens, as well as the devices the ThunderCats used when exploring New Thundera. He is also gifted with "mind-power" — the ability to create life-like illusions in other people’s minds; he used this for Lion-O’s Anointment Trial, but it puts a great strain on him. He uses whip-like bolas in combat, with which he can render himself invisible to the naked eye. In the episode "All That Glitters," Lion-O instructs Tygra, "If I do not return, you will be the new Lord of the ThunderCats." This verifies that indeed, Tygra is the second-in-command.
Where creators Ted Wolf and Leonard Starr described Panthro's character as being based on "strength" and Cheetara's character as being based on "speed," Tygra's character was described as being based on "integrity." Tygra has a romantic feeling for Cheetara (only in the comic books they developed a romantinc relationship and have two thundercubs in the Dogs of War arc).
Powers and abilities
Tygra is able to turn himself invisible to the naked eye. He also possesses mind power, which enables him to creates illusions that can deceive his opponents; using this power however drains him.
Tygra is also an intellectual, being the architect of the group, and has been seen making scientific research sometimes (he even works in a laboratory sometimes). He's grounded and calm, usually considering every aspect of a situation rather than rushing into conclusions or actions.
He also has some notable weakness: he cannot swim unless he is invisible, and twice he has shown himself vulnerable to addiction. By his own admission, he has self confidence issues, and has been shy since he was a child.
