Plusle have short tails with flat red plus signs on the end of them, while their cheeks are circular with plus signs voided in the middle. Plusle creates electrical pom-poms and sparks to cheer on its partners. Plusle's abilities in battle are basically the same as its cousin Pikachu except that Plusle has more Special Attack power than Pikachu and is slightly faster. However, Plusle is unable to use moves such as Volt Tackle and Slam.
