Pokémon Go 'Mega Ascension' choose a path — Mega Chesnaught, Mega Delphox or Mega Greninja?

Pokémon Go's Mega Ascension event has introduced a branching research task that requires players to commit to one of three Mega Evolution forms: Chesnaught, Delphox, or Greninja. This choose-your-path structure means trainers can only obtain one of the three Mega-evolved Kalos starters during this event window, making the decision consequential for their roster development and immediate gameplay priorities.

The limitation forces players to weigh which Mega form best serves their current needs, whether that's raid performance, type coverage, or collection preference. Since the event appears to lock players into a single choice, understanding the strengths of each option before committing becomes important for maximizing the event's value.

• Pokémon Go's Mega Ascension event uses a branching research path that restricts players to claiming just one of the three Kalos starter Mega forms.
• The choice between Chesnaught, Delphox, and Greninja carries meaningful consequences for team building during the event period.
