Wave Crest began life as an original character in a My Little Pony: Friendship Is Magic fanfiction as a pony analogue of Ryan Seacrest. This was to the effect that he was named "Ryan Seapony" by the author. In his fic of origin, he was judging a cooking contest being partaken in by a Mary Sue that also featured analogues to Al Roker, Emeril Lagasse, and Gordon Ramsay.
Thankfully for him, he and a few other OCs were all rescued to the PPC by Ian Nahinu and Amelia Keaton, who gave him the name "Wave Crest". Since then, he has joined the PPC, being partnered with Florestan and Eusabius.
Wave Crest, much like his original name suggested, carries himself in posture the way Ryan Seacrest might. However, Wave Crest is more of a trickster, as he loves to trade snark with anyone who wants to and he'll also troll people if he feels like it. He is not very experienced in the way humans think, though for some reason exactly what it is he doesn't know about human nature tends to be inconsistent as he knows more about some subjects and knows nothing about others.
