On the development of the character, screenwriter Meghan McCarthy said, "We just arrived at this idea of a character who had come from Equestria, and had not had the positive experience that Twilight (Sparkle) and her friends had .

Saldana says Celaeno "cares for her crew", adding, "She's a responsible, thoughtful, and empathetic leader .
