As Sylvester Sneekly, he is Penelope Pitstop's trusted and overly prim legal guardian; as The Hooded Claw, he is Penelope Pitstop's sarcastic and scenery-chewing ham of a nemesis.
As The Hooded Claw, he is assisted by the Bully Brothers, identical twins dressed in a parody of 1930s era British gangsters.
In the final episode of the series, one of the Ant-Hill Mob stole his Hooded Claw costume and, for whatever reason, he chose to retire from villainy rather than try to make a new costume, chuckling all the way.
The Hooded Claw is a master of disguise and quick-change artist; in addition to this, he is astonishingly talented at building over-elaborate death traps at a moment's notice out of anything at hand. His most notable talent is his unflagging and mocking laughter.
