Thank you! Terribly sorry for the delay. Natu and xatu are indeed fascinating pokémon.

Natu
The Tiny Bird Pokémon
Type: Psychic/Flying
Official Registration #: 177
Entry: As expected, natu is a tiny, bird-like pokémon known for its unblinking stare. It is said that natu are, indeed, constantly staring into the future, so its wide-eyed stare actually comes from the fact that it is not entirely paying attention to you as you stare at it but instead your future. This, combined with its underdeveloped wings, means natu is fairly easy to capture, as it will always be caught off-guard by your attempts to throw poké balls at it, and for it, escaping consists of hopping awkwardly away from you. Why it doesn’t simply notice that you’re about to capture it as it stares into your future (or why it never acts on any indication that you capture it) is still a complete mystery to the topmost scientists in the field of psychic pokémon research.

Xatu
The Mystic Pokémon
Type: Psychic/Flying
Official Registration #: 178
Entry: The evolved from of natu, by battle experience. Xatu is a large, four-foot-tall bird pokémon valued in various native South American cultures for its ability to see both the past and the future simultaneously—which, according to the peoples of that continent, explains why it constantly stares unflinchingly into the sun. While the ability to see both the past and the future simultaneously is indeed a useful ability, it has the nasty side effect of blinding a xatu to the present. Literally. Staring into the sun is generally a bad idea, and this writer would like to emphasize this point to any impressionable youth who may be reading this.
