We do not know the name of the Team Rocket Talent Scout, only her occupation. Her job is to find promising young trainers and convince them to join Team Rocket. She tests their worthiness by having them battle her Pokemon, Delibird. Her only appearance is in the episode "Dues and Don'ts", where she attempts to recruit Jessie and James. She doesn't believe them when they try to explain that they are already members.
Delibird is a very tough Pokemon. It froze Arbok, Weezing, and Victreebel solid before eventually being defeated by Wobbuffet. It attacks primarily by giving its opponent exploding gifts, though it also knows Blizzard. It runs errands for Team Rocket Headquarters as well, such as collecting debts from field agents.
