I don't know Bayonetta, nor do I tend to edit Syndra's page, so I can't say for certain. That said, "is a reference to" is a strong phrase. It's saying that Riot intentionally referenced other material. Since it's not obvious, I'd say that requires a quote or statement from a Riot employee.

Otherwise, the best you could say is "very similar too". (Again, I don't know if this is the case or not.)

Anyway, this isn't really the place to discuss specifics. But if you have any input for what the guidelines should be, please share.
