Anubis was Goa'uld that figured out how to ascend. He was helped by Oma Dessala, but when the Ancients figured it out, they tried to send him back. They however failed to send him back all the way. He is still a form of energy, being blocked between the two planes of existence. Since that day, Anubis is the only Goa'uld who got the knowledge of the Ancients.

However, after the weapon of Dakara had been used to destroy the Replicators, Daniel (who was in the RepliCarter's ship) awoke in a café (a virtual world between two planes of existence) where he met Oma again, and also "Jim", who actually was Anubis. He finally succeeded in convincing Oma to act: she engaged in a fight with Anubis and this was the last time they were heard of.
