Niantic has accidentally set Vespiquen as a male in Pokémon GO. Although this Sinnoh-region Pokémon hasn’t been dispatched yet, a number of dedicated Pokémon GO users have discovered that Niantic has made it so that Vespiquen has an equal chance of being male or female. However, this shouldn’t be possible as Vespiquen is a female-only Pokémon that exclusively evolves from female Combee.
