“An Instinctive Hero” is a Spark-themed set of quests in Pokémon Go as part of the season-long Rising Heroes storyline.
It runs from May 2-May 8, and though there are no event-specific spawns, there is a new Pokémon to find — Larvesta — while hatching eggs.
Meanwhile, unlike the previous event, “A Mystic Hero,” there is just a single research quest, as well as bonuses when hatching Pokémon.
