"Prior to the events of Pokémon Omega Ruby and Alpha Sapphire, Mr. Stone's grandfather, the previous president of the Devon Corporation, learned of the ultimate weapon and wished to use the same energy to help people and Pokémon. This led to Devon developing Infinity Energy. The use of this energy made Devon one of the top industries in Hoenn."

"Confidential documents can be found in Sea Mauville stating that Dock investigated the Devon Corporation, finding that they had used Pokémon bioenergy to create Infinity Energy."

Still not over the Infinity Energy article on Bulbapedia. The ultimate weapon made you, Devon.
