The Keroro Platoon using resonance in Manga

Resonance (共鳴 Kyoumei) is the sound that Keronians make, often in groups or pairs. The sound of the Keronian resonance is very unique and yet very strange to some Pekoponians. Some Pekoponians were seen doing the resonance as well (Fuyuki does FuyuFuyu and Natsumi does NatsuNatsu and so on). Resonances have a maximum amplitude frequencies that only Keronians and few Pekoponians make. When a Keronian does a resonance they inhale deeply and create a high pitched sound with noticeable symbols almost similar to Keronian was named after (cannot be seen to Pekoponians) coming out. It is possible that the Keronian resonance can last for about 10 minutes.

Only Pururu and Keroro have been seen using it alone, moreover she revealed that resonance has the ability to fix broken things, as she did restoring Keroro's bedroom.



  • Dororo is rarely in the resonance in the beginning of the series, mostly due to the rest of his platoon forgetting him or Dororo just flat out refusing.
  • Keroro's Father also uses the resonance to scare Viper as seen in episode 143.
  • The Garuru Platoon use the resonance on the Keroro Platoon Double as means of fighting.[1]
  • Angol Mois, despite Keroro saying she is an important part of their platoon, doesn't resonance a lot.
  • One time, the Keroro Platoon practiced their resonance because only platoons whom have successfully invaded could enter the contest.
  • Viper Momi , despite being a viper, is shown to have her own resonance, that being the wordsSquirm Squirm (ウヨウヨ Uyōyo). [2]
