To be specific, Brock can Mega Evolve his Steelix (the Onix he had evolved while it was not active on his team, since his brother has been helping take care of any Pokemon not active on his team), and Misty can Mega Evolve her Gyarados (its an irony, the one Water type she feared, but she got over the fear and this is a Pokemon she's constantly been seen with ever since)
