Lulu the Shiny Vulpix

Lulu is a fox-type Pokémon and is Ales Mansay and Boogey Boy's asisstant. She seemed to be a supporting character in her first appearance Gill Grunt Gets Kidnapped part 2, but she was later revealed to be an antagonist at the near end of the episode and also in Gill Grunt Gets Kidnapped Part 3 and 4.
