In the original NES localization, he was named Cristo while in modern localizations (from the DS remake onward), he is named Kiryl and he speaks with a thick Russian accent just like his companions whenever he has dialogue.
He is infamous in the original versions of the game for his AI, where he will always try to cast his instant kill spells first on bosses (who are likely to be immune in the first place) instead of doing his job of healing the party.
