* It could be assumed that Kokuran is the true Frontier Brain of the Battle Castle, due to Cattleya's place on a throne, even in the battle against them, her portraits in the castle, her appearing behind Kokuran and the term "Castle Butler". Therefore, Cattleya may be acting as a mistress and watching the battle from the throne. It is also possible that Cattleya is the Frontier Brain and just has Kokuran battle for her with her Pokémon.
* Despite their in-game sprite showing them both together, they do not participate in a [[double battle]]. This situation is much like the [[Twins]] of the [[Generation II]] games, and [[Jessie]] and [[James]] in
[[Pokémon Yellow Version]].
