Clemont's Luxray is the evolved form of Clemont's Luxio. It evolved at the Kalos Power Plant while it was under the control of Team Rocket and Clemont was trying to save it. It grew significantly during its evolving and Clemont had to hold onto it while it evolved fully. It learned to use Electric Terrain upon evolving which powers up Electric types and all the Pokémon in the plant fought back against Team Rocket.
