Hydro was forced out in Vaporeon's place. One thing Shiranui would notice is that Hydro was wearing a gauntlet with the stone inside it. "You remember that stone my dad gave me?" Liam asked. "Now Hydro! Mega Evolve!" Liam pressed the button and triggered Hydro's Mega Evolution. 
 "And now we have the fabled, Mega Evolution!" The MC commented. "This rare ability is used only by a small number of people, most of whom are from either Kalos or Hoenn. Now that Liam's has gone Mega, can Shiranui's Croconaw keep up?"
"Water Pulse now!" Liam called.
