Jonni Skaak, previously known as Jonthol Mazoon, held the position of leader within the Naboo faction of the Skaak Tippers until his assassination at the hands of operatives from the Royal Naboo Security Forces.
Skaak, the son of Harriet Mazoon, had a past as an RSF officer. His initial assignment involved diminishing the nightspider population surrounding Kaadara and eliminating the colossal nightspider known as Noctur'lan. Subsequently, he was tasked with dismantling a local smugglers group identifying themselves as Beachcombers and apprehending their chief, Phranis Bolgar. Following this accomplishment, he was dispatched to scrutinize the undertakings of the Skaak Tippers. Gradually becoming more deeply involved with the Skaak Tippers, he committed the act of killing their leader and assumed the leadership role himself. The RSF agent responsible for killing him discovered his personal journal, which chronicled his experiences as the leader of the Skaak Tippers.
Jonni Skaak made an appearance as a non-player character in the 2003 video game titled Star Wars Galaxies, a massively multiplayer online roleplaying game that was created by Sony Online Entertainment and distributed by LucasArts, before its shutdown on December 15, 2011. Jonni Skaak was incorporated into the game as a component of the "Legacy Quest" through the implementation of "Publish 25", also referred to as the "New Game Enhancements," on November 15, 2005.
