Ruby as a draconequus confronting Cosmos who is Discord’s Ex-Girlfriend and a villian in one of the IDW My Little Pony comic archives, Ruby tries to defend her close friend Discord from being chased and tortured by Cosmos but her chaotic abilities where not enough to stop Cosmos so Ruby was taken out so the only one with the power strong enough to stop Cosmos is Discord because he was born from pure chaos while Ruby was born a human, but still the canon of Discord stopping Cosmos is canon in the IDW comics.
