also: ビクタ
noun
A katakana rendering meaning a victor or winner. In ordinary Japanese, 勝者 or 優勝者 is usually more natural unless a foreign-style term, title, game term, or translation flavor is intended.
このゲームでは、最後まで生き残ったプレイヤーをビクターと呼ぶ。
In this game, the player who survives to the end is called the victor.
Another katakana word meaning winner; generally more recognizable in everyday modern Japanese than ビクター for this sense.
