"Gengar against Gengar, huh? Then let's see whose is stronger!" Liu Qing's fighting spirit burned even hotter as he commanded, "Gengar, Shadow Ball!"
At his command, Gengar brought its hands together and swiftly gathered energy into a Shadow Ball, firing it straight at Agatha's Gengar. Facing the rapidly approaching attack, Agatha's Gengar flattened like a folded sheet of paper, becoming a thin layer pressed against the ground. It quickly dodged the attack and moved toward Liu Qing's Gengar.
"Looks like this Gengar is very good at using its natural abilities, too!" Gengar was a Shadow Pokémon, but not every Gengar could turn itself into a shadow to move around. As far as Liu Qing knew, only his own Gengar and Agatha's had demonstrated that ability.
Liu Qing's Gengar was an old ghost that had lived for thousands of years. Agatha's Gengar might not even match its intelligence. Even without a command from Liu Qing, it knew how to respond. It pressed both hands against the ground, sending rings of black light rippling outward from them. Like a cleansing agent, the light swept the shadow-form Gengar off the ground, while Liu Qing's Gengar turned into a streak of light and shadow and swiftly chased after it.
"Gengar, use Shadow Ball!" Agatha was somewhat surprised that her Gengar's shadow ability had been countered. Watching the other Gengar rapidly approach, she quickly responded.
The black light was merely another, dispersed application of Shadow Ball's power and had done little damage to her Gengar. By now, it had begun to recover. Seeing its opponent closing in overhead, it quickly stood up, brought its hands together, formed a Shadow Ball, and hurled it straight at the approaching Gengar.
"Shadow Ball!" Since Gengar had dared to chase after its opponent, it was naturally prepared to respond.
