I like a good design challenge and coming up with new characters, but fair warning: I usually dont do much with them; and in this case especially, cause I dont really care for the ship itself. (Frankly, I dont care much for Discord shipping in general. I dunno, it just doesnt work for me.)  
So you guys can play around with him as you like.
 
Concept:  
Im not exactly sure how the conception worked, but Discord definitely couldnt resist meddling with the final product. He thought itd be fun to give his offspring parts of the most dangerous animals in Equestria in the hopes that since he wasnt allowed to cause all that much chaos himself anymore, his son would.  
Of course that plan not only backfired because its still also Fluttershys offspring, so hes got her friendly and laid-back character, but also cause those animal parts make many of Equestrias most dangerous animals see him as part of their own race. Coupled with Fluttershys inherent animal-friendliness this means he can play around with Timberwolves etc. like they were his personal puppies.  
Hes taken it upon himself to be a travel guide in the more dangerous parts of Equestria, entertaining ponies on the way with stories about his parents and their friends. A big, cuddly sweetheart.
