Who's that Pokémon?

Who's that Pokémon? (だれだ？) is a segment question and answer of the Pokémon anime.

The original Japanese version has this type of segment with multiple variants, being called "Who's that Pokémon?" in the dub. The dub has a variant called Pokémon Trainer's Choice for many episodes of the Advanced Generation dub seasons, although the dub has no segment for Diamond & Pearl episodes. There are also episodes of the original version that would use a standard eyecatch in the middle of an episode rather than this type of segment.
