Zanner

The partner and older sister of Oakley. They both appeared in Pokémon Heroes.

Both she and Oakley are named after Annie Oakley, in the same manner as the Rocket duos Jessie and James, Butch and Cassidy, and Attila and Hun.

Unlike her younger sister Oakley, Annie is a little less concerned with the task at hand, and appears to be slightly more vain. Prettier and more suave than Oakley, Annie is enchanted by the beauty of the Soul Dew, rather than the abilities of the Defense Mechanism of Alto Mare, or capturing Latias and Latios for Giovanni; she even screams that her outfit is ruined when she falls into a canal.

Ditzy as she appears, Annie is more in control than Oakley is, as Oakley goes somewhat mad with power when commandeering the Defense Mechanism of Alto Mare (DMA), despite Annie's concerns about using it.
