This pretty face is indirectly the reason Mister Clever exists. 

Well not the canon Mister Clever since I’m pretty sure there are no talking alicorns in Doctor Who…at least not on Mondas. 

Either way this is King Argentum (call him a Prince and he will kick you into his dungeon…along with a lot of his people) the only Alicorn on Mondas, and thus he’s their self-proclaimed king… and he kind of controls the planet’s orbit so the ponies living there aren’t going to argue with him…

until a certain event happened and yeah…

there’s a reason there were no Cyber-Alicorns before Clever’s time.
