Kids summary (simpler)Tap to expand
Duosion is the Mitosis Pokémon — Psychic middle stage between Solosis and Reuniclus. In Pokémon GO it is usually candy on the way to Reuniclus — not a finished raid attacker. Psychic helps against Fighting and Poison; Bug, Ghost, and Dark hit Psychic hard. Evolve Solosis up the line.
