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.
Sierra was the second Team GO Rocket Leader encountered by one of Professor Willow's assistants, following Cliff. 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.
On November 5, 2019, Sierra sent the following message to Spark:
- "Spark. Your naïve positivity is laughable and will be your undoing.
- The world is so very cruel.
- I’ll make sure to remind you soon."
On November 12, 2019, Sierra was tracked down by Spark using the Rocket Radar and was challenged to battle. The battle resulted in a close loss for Sierra as Spark ended up with only one Pokémon remaining.
On July 26, 2020, during Pokémon GO Fest 2020, Sierra battled Spark. Spark initiated the battle by sending out an Elekid, while Sierra sent a Shadow Houndoom. Houndoom started the fight by using Bite but Elekid knocked it with a destabilizing Thunder Punch. In the end, Spark won the battle when Giovanni recalled Sierra to him along with the other Team GO Rocket Leaders.
Sierra uses a team of three Shadow Pokémon in a Trainer Battle, each independently and randomly selected from separate pools. During battle, Sierra will always use a Protect Shield whenever possible. Upon being defeated, Sierra will abandon one of the Shadow Pokémon used in battle.
The following lists the possible Pokémon used by Sierra since June 21, 2023. Green-colored cells denote the Pokémon that will be encountered during the bonus challenge. These Shadow Pokémon have a chance of becoming Shiny, as denoted by the icon.

From September 2 to September 30, 2023, Sierra appears in five-star Shadow Raids on Saturdays and Sundays.
