There was a reject dragon hatchling that was left for dead because of his feathery wings. A Pegasus pony found the hatchling while she was tracking the dragon group, she took him in and was given a medical examination. The hatchling was growing happy and healthy under the care of the Pegasus pony who found him. While trying to name him, the hatchling sneezed, causing a storm. She saw how the dragon was connected to the storm when he sneezed, she named him 'Storm Breaker' (He's the father of Whirlwind)
Now for Spike's, Spike never knew his biological parents because they were slaughtered by the remnants of Malefor's army after the war. They would've smashed his egg until Master Eon arrived and saved him. The portal master saw him as a legendary purple dragon, that was odd because only one was born once every 200 years. But it was four years since the previous purple dragon hatched and was now missing. After meeting Starswirl the Bearded and Fausticorn, Eon wanted Faust to take the egg to Equestria and give the hatchling a good home. She did, but Faust saw 978 years of Princess Celestia's sadness of losing Princess Luna, she placed the egg right beside the Sun Goddess as she slept and returned to Skylands to end up captured by Kaos.
The only problem with that is those two heartless bastards known as Sherclop Pones would write the story so that his mom dies. Nothing good can happen in the Friendship is Witchcraft world. That world is Equestria's version of Hell. I'm convinced. That abridged series is a Satanic Abomination and an insult to Lauren Faust and to all the bronies and pegasisters out there.
SCREW YOU SHERCLOP PONES!
