He know that not everyone want to be his friend, because they are afraid of him and everyone think every changeling are evil, except him and they doesn't know, so he transform himself as a male crystal pony named Crystal Hoof, and he make friend with every pony, but then he approached Flurry Heart (Tabitha St. Germain) he accidentally reveals himself to the pony, Spike didn't take his defense at first because every pony refuse to let him explain, heartbroken he go hide in his cave, Spike tried to apologize, but he refuse at first, then Spike tell him that he was his only friend and go save him, when they return to The Crystal Empire every pony tried to chase him off again, but Spike convince them that he's not evil at all, finally, malicious,after earning the song of Spike they finally welcome him to the Crystal Empire.

Personality
Before his redemption, Thorax was a sadistic, cruel, malicious, sinister, evil, and wicked changeling who would kill his victims without a second thought. He is very handsome, seductive, aggressive, deadly, and yet dangerous whenever he disguises himself as some pony else. He likes to mess with people's minds or keep his victims company like Dr. Henry Wu (B.D. Wong) and Flash Sentry (Vincent Tong) while impersonating Victor Hoskins (Vincent D'Onofrio) and Sunset Shimmer (Rebecca Shoichet).
