Should You Choose Spark or Sierra in the Pokemon GO Holiday Part 1 Research?

Author : Lucy Update:Jan 04,2025

In Pokémon GO's Holiday Part 1 branching research, trainers face a crucial decision: assist Spark or Sierra. This guide clarifies the choices, helping you optimize your holiday gameplay.

Pokémon GO Holiday Part 1 Research: Dates & Details

While the official Niantic announcement omits the free event research, it's available from December 17th to December 22nd, 9:59 AM local time. This "Holiday Part 1" research features three stages. After completing the first, you'll choose between aiding Team Instinct's Spark or Team GO Rocket's Sierra.

Should You Choose Spark or Sierra?

The core difference lies in the Pokémon type focus: Ice-type for Spark, Fire-type for Sierra. Your choice depends on your preferred Pokémon and desired reward encounter.
