The version of Merlin from the universe of Fate/Prototype. According to this universe's Saber, this Merlin is actually female.
She makes a vocal cameo in Fate/Grand Order when Prototype Arthur uses his Noble Phantasm. Amusingly she is voiced by Kawasumi Ayako, who voices Artoria (and her variants). She later made her first playable debut in Fate/Grand Order Arcade in September 2020, establishing an official design.
In summer 2022, Prototype Merlin became a summonable Pretender-class Swimsuit Servant in Fate/Grand Order itself, going under the alias Lady Avalon.
