“You will be the first to die!”
—O'Neill's battle quote
O'Neill is a boss character in Fire Emblem: The Sacred Stones. He is a squad leader in the Grado Imperial Army who was present during the siege of Castle Renais. He and his two Fighter sentries had given chase to Eirika and Seth as they were entering Frelia. Eirika was just given a Rapier and used it to fend off the soldiers. Seth attempts to protect Eirika despite his previous injury by Valter. Eirika then comes and defeats O'Neill, though getting a wound herself in the process.

O'Neill is a boss character who goes near units who go in his attack range. The Tutorial makes it easy to beat him, and Seth does not even lose any health in the level, though he does start off with 13HP after the fight with Valter.
When playing on Normal Mode, players should take caution when using Eirika to defeat O'Neill. While Batta is completely incapable of defeating Lyn in her campaign's Normal Mode, O'Neill has a surprisingly decent chance of defeating Eirika should the player choose to underestimate him.
—O'Neill's death quote.
- O'Neill is actually slightly faster than Gheb, a promoted unit who is a boss in the much later Fort Rigwald chapter.
- O'neill has the generic fighter palette with the exception of darker brown hair. However in the game data, O'neill's unused palette when on the player's side has a black uniform, matching his shirt.
