“A Valorous Hero” is a Candela-themed set of quests in Pokémon Go as part of the season-long Rising Heroes storyline.
It runs from May 11 to May 17, and though there are no event-specific spawns, there is a new Pokémon to battle — Mega Pinsir — in raids.
Unlike the previous event, “An Instinctive Hero,” there are two research quests to complete — one Timed, and one Special.
