Dragon Claw is in the middle of a fucking ridiculous hormonal crisis, brought on by that one party where the Mane Five were acting like total sluts, and now he's acting like a total pervert. This isn't a joke, though; if Dragon doesn't make the bed rock (rock the kasbah, rock a world, blow a mind, play "One-Eyed Snake and the Empty Cave") with one of the Mane Five, he'll become a Reshiram, which could destroy everything and then rape all the girls as unnecesary salt in their wounds.
The image is not mine, so I have to thank who changed it, even though I didn't ask him for permission (it's from Jessie-Anime on deviantart, and it's called "Badass gijinka reshiram, but that isn't my human form", or "BGR,bTImHF" for short).
It's a kinda-sorta sequel to "Congratulations, Your Frienship Has Evolved Into Love", but is incredibly loosely related, and only for the "Yes" Answer

Thank you, Lord of Nothing, for the description
