Shiranui's quarter final opponent sent out a Shuckle. "Hoshi, I choose you!" Shiranui responded by opening a star-labelled Poké Ball. Stars burst out of the ball and two of them joined together to form a ten-pointed star that metamorphosed into a Starmie.
"Shuckle, Double Team!"
"Hoshi, Confuse Ray!" Hoshi's core rapidly blinked through the seven colours of the rainbow as the Starmie let off a bright flash that left Shuckle confused. Shuckle hurt itself in its confusion and that caused its trainer's points to take another hit.
"Shuckle, Sandstorm!"
"Hoshi, Reflect Type!" The Starmie changed its type to match Shuckle's, changing the colour of its limbs to ecru and sticking with yellow for the area around its core. Shuckle was able to summon a sandstorm and thanks to Hoshi's type change, neither battler took any damage from the weather.
"Shuckle, Earthquake!"
"Hoshi, you may fire when ready." Hoshi's core glowed a bright lime green as laser beams issued forth from all ten of its limbs, converging into a focal point in front of its crystal core. A powerful beam was fired from the focal point and nailed Shuckle squarely for a hit. Shuckle withdrew into its shell and slammed itself onto the stage, causing an earthquake that shook Hoshi for a decent amount of damage.
"Shuckle, Gyro Ball!"
"Hoshi, Rollout!" Shuckle snapped out of its confusion and both battlers started spinning towards each other and at impact, the two received the same amount of damage.
"Shuckle, Shell Smash!" Hoshi's spin speed was at a steady climb as the Starmie charged in for another hit. Shuckle made cracks in its shell, but its defence stats went up whilst its Speed and Attack stats took a sharp drop due to its Contrary ability "Power Split!" Hoshi zeroed in for a third hit and nailed Shuckle right in its shell crack for a critical hit. The damage was just enough to knock Shuckle out and Shiranui advanced to the semis.
