From Bulbapedia, the community-driven Pokémon encyclopedia.
Ancha (Japanese: ツミキ Tsumiki) 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, or if it is a situation similar to that of Nurse Joy and Officer Jenny.
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.
Her name comes from "anchor", a common title for newscasters.
