Oong

Oong was a Protoss High Templar who witnessed the Zerg attacks on the Koprulu Sector.

He reported to the Elders or Wise Ones (presumably the Conclave) that these creatures were similar to ones found in ancient Protoss histories, which recounted the last days of the Xel'Naga, which now sought to destroy the Protoss.

He requested 5000 Templars to assist him in investigating the creatures and to fend off any uncooperative Terrans.

He was sent on the expedition. 1996-10-30. StarCraft (pre-release Protoss page). Blizzard Entertainment. Accessed 2008-01-26.

Considering the storyline changes in other information from the era, such as details of the Xel'Naga's "last days" gleaned from the Overmind and Tassadar's status as leader of the Expeditionary Force, Oong's status is probably non-canon.
