ThunderCats wiki

WilyKit is the female Thunderkitten, the sister of WilyKat, and she is the youngest of the Thundercats. They were close to Lion-O's age when escaping Thundera before its destruction. However, their suspension capsules aboard the Thunderian Flagship worked and maintained their age while Lion-O's capsule did not.


WilyKit and her brother WilyKat were among the Thundercat Nobles leaving the dying planet of Thundera. The Thunderkittens were given new clothing and weapons by Jaga to help them adapt in their new home. The Thunderkittens left with the other Thundercats when the Mutants arrived and fought them back using their new weapons.

After the ship crashed on Third Earth, the Thunderkittens helped to fight back the Mutants once again, surprised to see how much Lion-O had changed.

WilyKit and Kat helped a Wollo who was being robbed, pursuing the robbers after they stole a gold bracelet from the Wollo. they arrived at the mysterious Tower of Traps, after which WilyKat was captured. WilyKit journeyed with Lion-O to the top of the tower, avoiding many traps on the way, before rescuing WilyKat and fighting some monstrous Gargoyles.

When the third day of Lion-O's Anointment Trials occurred, it was time for the Trial of Cunning. As the most cunning and crafty of the Thundercats, it was WilyKit and WilyKat's duty to try and stop Lion-O. The Thunderkittens set many traps for Lion-O within the Maze of Infinity , but Lion-O was able to avoid them all, while also having to battle the attacking Mutants. In the end, the Thunderkittens were caught in one of their own traps which backfired, and Lion-O rescued them with the help of the native creatures before they all ran to the exit. The Thunderkittens tried to beat Lion-O to the exit, but he had tied their ankles down, and he was able to beat them out, making it through the trial of cunning.


WilyKit is a very adventurous young lady, she spends most of her time with her brother WilyKat. The pair of young thunderians are playful and active. She does not go on as many missions as the older thundercats.
