From Bulbapedia, the community-driven Pokémon encyclopedia.
Ancha is a Newscaster who appears in Pokémon Colosseum and Pokémon XD: Gale of Darkness.
Ancha's main role in Colosseum is to report on the mischief Fein caused throughout Orre, after which she is not heard from again. Identical-looking Newscasters also appear on television news broadcasts and during "The Under Time" with Venus, though it is unclear if they are all related.
Ancha returns in Pokémon XD as the star newscaster for ONBS, a job that she takes very seriously. She appears to have many fans from all over Orre. Even Cipher has at least one Ancha fan in their ranks, as a Cipher Peon attempts to obtain her autograph during the ONBS takeover.
