That guy is Zargnon Lix, Intergalactic Criminal and Founder of Smugglers Against Jugglers.
Man this comic really blew up.
The red four-armed lady’s name is Space Dread. She is trans and she wanted to be a juggler but grew up to be a bounty hunter/assassin instead.
Zargnon Lix is (was?) the guy wearing the I Hate Juggling shirt. He was a wanted criminal who also happened to hate juggling. He’s dead now.
