Cubit Foxtar (キュービット・フォクスター Kyūbitto Fokusutā) is one of the bosses of Mega Man Zero 3. Foxtar is one of the Eight Gentle Judges modified by Dr. Weil into his Weil's Numbers, a Mutos Reploid based on a kitsune, the nine-tailed fox. Cubit has nine remote control options to attack and can create flaming mirages, preferring to use strategy to defeat enemies instead of physical fights. Foxtar looks down on Tretista Kelverian and Deathtanz Mantisk with contempt due to their brutal fighting skills. Before his creator "upgraded" him, he was strict but kind, as shown when conversing with Childre Inarabitta after Elpizo's trial. When Dr. Weil returned and upgraded him however, he was mocking and cruel, saying that Weil's upgrade was "libertaing", showing that he liked his real personality and not the other one. Zero fights him to shut down the Baby Elf factory, which was later revealed not to be needed since the Messiah merged with the Dark Elf was just fine. He was later revived for another round but was defeated again, although he told Zero to not throw a fit since he's no hero and God of Destruction, giving a final hint at the Messiah's true idenity...

An image of Cubit Foxtar appears in Mega Man Zero 4 as one of Dr. Weil's first form attacks, using the Fire Rain attack, where Cubit releases six fireballs.
