While Nebby in his unevolved form is pretty unremarkable, turning into the avatars of the Sun or the Moon as Solgaleo or Lunala makes them pretty interesting and much more powerful. These Pokemon are very strong, with a lot of resistances and immunities to speak of. Lunala is resistant to poison and psychic attacks, and immune to normal and fighting moves. However, it takes 4x the damage from ghost and dark attacks. Solgaleo takes 2x the damage from ground, ghost, fire, and dark attacks. However, they are immune to poison attacks and resistant to normal, flying, rock, steel, grass, psychic, ice, dragon, and fairy attacks. Each also possesses high stats and a wide range of attacks to choose from, so no matter when you get Nebby, you should at least try to have a spot for him on your team. It might be a tough move letting one of your big 6 go, but considering that she gives you Nebby in his evolved form for free, and all you need to do is capture him, that’s worth it. Especially since there might be some tough battles ahead and you’ll need all the help you can get to pull out a few wins!
