Sierra (Japanese: シエラ Sierra) is one of the Leaders of Team GO Rocket in Pokémon GO.
Sierra was the second Team GO Rocket Leader encountered by one of Professor Willow's assistants. Spark, while rescuing Eggs from potential PokéStop invasions, ran into Sierra during his mission. Sierra mocked Spark's efforts in rescuing the Eggs, which prompted him to challenge her to battle. However, Sierra noticed that an unprepared Spark had not brought any Poké Balls, and dismissed his challenge as she walked away.
A street-smart loner, she has grown up under difficult circumstances, allowing her to learn martial arts. As she rose within the ranks of Team GO Rocket, she became Giovanni's most trusted confidant.
