Talk:Fate/EXTRA CCC Collaboration Event/@comment-28424965-20170424122028/@comment-27971189-20170425054107

EMIYA Alter is there because his girlfriend said by his Bond Level is CCC character, not because he's just another EMIYA.

Proto Cu and Cu Alter are different Cu.

Cu Alter is Grail creation, Proto Cu isn't the same Cu with Lancer Cu just like Proto Arthur =/= Arthuria. Caster Cu is the same with Lancer Cu but as Caster Cu said himself, FGO is the first time he is summoned as Caster; considering the circumstances, it could be BB's system only recognize Lancer Cu.

Gil recognized by the Mooncell is also only Archer Gil, not Caster Gil.

Nero Bride is there because she is the same Heroic Spirit Nero, as Nasu said, the difference between both Nero Bride is that FGO Nero Bride affection is going to Ritsuka instead of Hakuno.

Berserker Vlad is not there because both recognize each other as different person; Halloween event mentioned this with him saying "I am not the Dracula, I am the warrior Vlad!"

The remaining you mentioned is event-only Servant, such as Lancer Tamamo, Caster Elizabeth; they exist by FGO universe 'uniqueness' so its normal if they didn't have part on this.
