“More info about Summer Wind - first-born son of Fluttershy and Big McIntsoh
 
Growing up on a farm outside actual town, with a mother like Fluttershy, Summer Wind was growing up with strong love for nature. Despite being rather strong colt and perfoming all needed work at Sweet Apple Acres, Wind has never been a farm pony at heart (unlike his younger sister), he reminded more of Flutters, being “mommy’s son”. Summer Wind formed a very strong bond with his mother since early childhood. They understood each other easily, and Wind would do everything to make his mom smile or to protect her if needed.
 
There were other sides of his attitude to Fluttershy as well. So, he couldn’t bear any kind of offense against his mother, which sometimes lead to extreme overreaction. If something like that occured, normally gentle and even-tempered Summer Wind immediately lost his temper and entered his own state of uncontrolled anger (call it “Summerrage”). While it worried his parents and friends, Wind himself didn’t pay much attention to these bursts of anger, until one day he accidently broke tooth of his friend Rainfall (daughter of Rainbow Dash), who only tried to calm him down, while he was in his rage state again. So, only after he hurt one of his close ponies, Summer Wind understood that something is wrong here, and began working on himself in this aspect.
 
His mother often took him on a walk in Ponyville’s outskirts, and this glimpses of wilderness always fascinated little colt. No wonder that his dream was becoming a naturalist and collecting comprehensive information about all types of animals of Equestria (and possibly other places as well).”
