Niles

Niles (ゼロ, Zero) is a playable character in Fire Emblem Fates and originally start out as a non-playable character in the first release of Fire Emblem Warriors.

Personality
Niles enjoys watching people suffer, especially those from the upper classes. He may easily become agitated if provoked. After swearing loyalty to Leo, he abandons his criminal ways yet maintains a shady image. Niles is also very flirtatious, often making statements filled with innuendos. This applies not only to women but also men as demonstrated by his habit of getting into Leo's personal space just to tease him. (Owain – who met Leo and Niles as Odin – is Leo's other retainer, and they reference this in their Support.)

Fighting Style
Niles' unique Crest is Lethality, a classic Fire Emblem skill typically available to Assassins. Unlike in regular Fire Emblem games, where it offers the chance for the user to instantly defeat an enemy when they deal damage, in Warriors, it has a Luck-based chance of increasing the power of combos and Critical Hits.
