Spark vs Sierra: Best Choice in Pokemon GO Holiday Part 1 Research

Author : Charlotte Update : Apr 17,2025

In the world of *Pokemon GO*, players often face crucial decisions in branching research paths, and the Holiday Part 1 event is no exception. This time, trainers must choose between aiding Spark of Team Instinct with his Pokemon research or pursuing Sierra of Team GO Rocket. With little guidance from Niantic on which path aligns best with your Holiday Part 1 goals, making the right choice can be challenging.

Pokemon GO Holiday Part 1 Branching Research Dates

Surprisingly, Niantic's official announcement for the Holiday Part 1 event only mentions Field Research and the Paid Timed Research option, leaving out details on the free event research story. However, rest assured that this event does include a free research path for all trainers, running from December 17 to December 22 at 9:59 AM local time. This Holiday Part 1 research path comprises three sections, and after completing the first set of tasks, you'll face the pivotal decision: help Spark or track down Sierra.

Should You Pick Spark or Sierra in Pokemon GO Holiday Part 1 Event Research?

In typical branching research fashion, the differences between choosing Spark or Sierra are not drastic. Your decision will hinge on two main factors: the type of Pokemon you wish to focus on catching and the reward encounter you prefer. Let's delve into the specifics of each path to aid your decision-making process.
