Choosing Between Spark and Sierra in Pokémon GO Holiday Pt. 1

In Pokemon GO's Holiday Part 1 branching research, trainers face a crucial decision: aid Spark or Sierra. While Niantic's official announcement omits this free research, available December 17th-22nd (9:59 AM local time), it's a key part of the event. This three-part research culminates in a choice between assisting Team Instinct's Spark or Team GO Rocket's Sierra.

Choosing Your Path: Spark or Sierra?

The core difference lies in the Pokémon type focus and reward encounter. The choice isn't drastically impactful, but it significantly alters your in-game strategy.

Spark's Icy Challenge

Opting for Spark directs your efforts towards Ice-type Pokémon. Completing Part 2 rewards an Alolan Vulpix encounter.

Spark's Research Tasks: Part 2

Spark's Research Tasks: Part 3

Note: Part 3's rewards (including the Sandygast encounter) remain consistent regardless of your choice.

Sierra's Fiery Pursuit

Choosing Sierra shifts the focus to Fire-type Pokémon, culminating in a Shadow Vulpix encounter in Part 2.

The Verdict: Your decision hinges on your desired Vulpix variant (Alolan or Shadow) and preferred Pokémon type for catching during the event. Pokemon GO is available now.
