When the Slyren reaches 100 MPH, it starts singing within a few seconds of its tranformation. Those who are within its range fall asleep. It can also sing while in protoform, as seen in "Snowdance" that a nest of the Slugs keep the Ice Ogres hibernating. Eli used the one that he caught to put all the Ogres back to sleep.  Pronto used Eli's Slyren to save Danna Por from The Gentleman's Geoshard. It is a very powerful slug, as it can break the crystal of a Geoshard and put the Ice Ogres to sleep, and can easily put someone to sleep.

A famous Slyren is Dozer, who belongs to Eli Shane.

A ghouled version of Slyren has not yet been seen in the show.


When transformed, the Slyren has the ears of a bat, frog-like arms, and a fishtail. It has a yellow-colored belly but it's mostly colored blue. Its tail and mohawk are colored turquoise.

    • I say the ghouled Slyren should be called the Klaxen slug, because Slyren is a play on siren, while Klaxen is a play on the Klaxon type of alarm.
