Octavius Nixon Sukhoi was a member of the Ship's Watch (Internal Security) on the Pathfinder Ship Pegasus . He was a native of the planet Republic , and a member of the Notorium, the Republic Secret Security Service (a.k.a. 'The Centurions'), where his codename was 'Constantine.'

In Book 02: EdenWorld , Sukhoi/Constantine, assisted in the search for Trajan Lear in the UnderDecks of Pegasus when he was kidnapped during his walkabout.

In Book 04: Winter , Sukhoi was sent to the surface of the planet Winter to assist in the investigation of the murder of Clinton Manchester. Later, he was tasked to assist local authorities in the search for Phil Redfire when he disappeared from his jail cell.

InBook 05: Aurora , he was sent to the Supah Al-Fareek Synerplex to demonstrate various weapons to corporate executives, as part of Goneril Lear's bid to secure Aurora as an ally to Republic.

In Book 06: Crucible , he was ordered (as a Centurion) by Geoneril Lear to eliminate Keeler as the commander of Pegasus. He was then ordered by Bill Keeler (as a member of the ship's watch) to take the mutinous Goneril Lear into custody. He weighed his conflicting loyalties, but ultimately decided to side with Lear; a choice he came to regret as it became increasingly apparent that she was deranged. He wanted to remain on Pegasus when the cruise were split, but Keeler ordered him to leave, saying he could no longer trust him.
