The Ancient ThunderCat Flag is one of the four artifacts that were used by the ThunderCats to prevent New Thundera from self-destructing, and to return the planet to its former glory.
The flag is black in color with an angular red streak running across it.
Following the instructions of the Guardian of the Book of Omens, WilyKit and WilyKat take the flag in the Whisker to the Iron Glades. When they presented the flag at the 24th hour, the entire iron forest was changed back to evergreen woods of real pine trees.
