Plusle is Solana's main Pokémon. During Solana's mission to protect Celebi, Plusle has been relied on mostly for its Helping Hand technique to power up the Pokémon caught by Solana using the capture styler. When Team Rocket came, Solana commanded Plusle to use Thunder Wave to destroy their mecha. In its next appearance, Plusle, along with Ash's Pikachu, was affected by the geomagnetic disturbance caused by Deoxys. For some unknown reason, it was not seen in Pokémon Ranger and the Kidnapped Riolu! Parts 1 and 2.
Plusle's known moves are Thunder Wave and Helping Hand.
Deoxys crashed onto the planet and started causing disturbances in the area, due to it feeling weak. Solana wanted to catch it so she can restore its strength. However, the only way to catch it was to have it in Normal Forme. With the help of Ash and his friends, Solana was able to catch it and everything went back to normal.
Solana's Spanish name is a reference to the moon, rather than the sun like all her other names. This is most likely due to the fact that the deity after which she is named sounds similar to her English name. Lunick's Spanish name is likewise a reference to the sun.
