Afaik, Nasu himself said she's an Archetype (Archetype - Earth), with Crimson Moon (her "alter ego", though actually her ancestor and the original "True Ancestor" from which all True Ancestors were based on) being the TYPE-MOON. I doubt we'll be seeing Arc anytime soon simply because given how Fate is moving things, we'd need to go into NOTES territory for the TYPEs to start appearing, although we have already been hinted that they will likely show up at some point (The Ultimate one was mentioned at some point in the story, forgot when, and it refers to ORT, the TYPE-MERCURY, also being the 5th Dead Apostole, and as a small reminder, Beast IV, aka Primate Murder, thet "what if" Fou has already appeared as a story plot inflexion during the epilogue of Solomon).

The reason she appears as a Berserker in the mooncell is because of an error within the system, since she "can't be copied, soul or not", so her avatar assumes the closest possible form and shape to her (she's the Archetype-Earth, the -potential- protector of the planet, and is always given 1 single point of strength above any threat that appears to endanger the planet, which is sort of close to the Berserker class, since it's "always" above other classes in terms of power), or something around those lines anyway.
