A Craft Essence in Fate/Grand Order featuring a chibi variation of Cu Chulainn Alter. It originally appeared in the game's "Prisma Codes" event. He also shows up in both Anastasia and Paris's Valentine events, forming a rivalry with the dolls they give the protagonist.
This tag is specific to the chibi version seen in FGO. If he is depicted as a non-canon chibi (like post #2348112), don't use this tag. Also, do not add the Cu Chulainn Alter tag if Mini-Cu is by himself. They are treated as separate characters and should only be tagged together if both are present in the image.
