Flamestone is a heroic Jewel Lord and a hot-blooded crimson fighter. He has the ability turn sunlight into blasts from his hands. He turns into a ruby and carries a sword.
Flamestone was featured in the 2016 Ask Vector Prime story Echoes and Fragments, set during the events of The Transformers: The Movie. The manipulations of the evil Gong and Sideways resulted in various GoBots, Rock Lords and Starriors swapping places with characters during the events of that film. After Boulder's tribe allied itself with the Autobots and Guardians Flamestone and Sunstone danced with Arcee and Springer.
In Fun Publications Transformers: Renegade Rhetoric episode 43, "Of Rocks and RoGuns Part 1", Scope stumbled upon the lost city of Clastixandria where discovered the comatose forms of the Jewel Lords, hooked into a pulsating crystal.
