From Bulbapedia, the community-driven Pokémon encyclopedia.
Angela (Japanese: イチコ Ichiko) is a character of the day of the anime who appeared in the episode From Cradle to Save. She is the teacher of a Pokémon Ninja School located in a forest, and is a very skillful ninja.
Ash and his friends met her when Evian took them to the Pokémon Ninja School. Brock jumped toward her, but seconds later, she appeared as a substitution of herself as a log with similar clothing. She revealed herself in a nearby treetop, amazing all the students with her actions. She then presided over a training session with Ash and his friends as special students.
When the school was under attack by Team Rocket, Angela sent her Shiftry into battle, destroying the trio's mecha. Jessie then attacked her by running around uncontrollably and creating many clones of herself. Angela then had Shiftry use Double Team, which created a Whirlwind effect, rotating Team Rocket at a high speed. An Ariados then entangled the trio with its web, trapping them inside. They were then rolled off a nearby cliff with the ball of webbing.
