- “Q: What's a Sharquoi?”—Fizzguy47
- “A: Very freaking dangerous.”
The Sharquoi is a Covenant-related entity mentioned by a Sangheili in conversation. "I suspect we are forcing the Humans into a tighter arena than they care to fight in - soon we may be able to use the Sharquoi." Exactly what the Sharquoi is has yet to be determined, though it has been theorized to be anything included in Halo 2 or that was planned to be included.
