Personality/Bio-
Brash and blunt, Wild Blue takes after his parents. He's got a need for speed, and racing is his life. He is very headstrong and stubborn, and will go well out of his way to complete a challenge. After all, nopony could make up any challenge that Blue couldn't do. Blue is in training to become part of his mother's flying team, the Skydashers. He knows his parents are already incredibly proud of him, but he wants to give them more to be proud of.
Blue is slightly narcissistic. This is mainly due to his talent in flying and all of the praise he gets for it. A natural daredevil like him just sort of becomes egotistical after a while from that sort of thing. Blue knows he shouldn't flaunt his accomplishments, but he just can't help himself sometimes.
Blue thinks he is way tougher than he actually is, which often gets him into a lot of trouble. He tries to do things that nopony has ever done, or could ever do, and it has resulted it countless trips to the hospital. Rainbow is a very stressed out momma due to this. However, Blue doesn't let his injuries get him down and he gets right back to life. He also likes to use his various injury stories to impress ponies.
Blue is incredibly brave and valiant, and would do almost anything for those he cares about. Whether brave or stupid, he'd charge headlong into battle to protect his family. As a foal, Blue dreamed of being a royal guard, and even though that dream faded as he got older, he still does everything he can to keep the ponies he loves safe and happy.
Relationships-
Blue and his parents are extremely close. He absolutely adores the both of them especially since they all share brash and confident personalities. His parents support him in every way and are always there to cheer him on in his races. Blue looks up to the both of them greatly and has made it his goal to be as awesome as they are.
Blue and his half-brother, Stratus Storm have a very difficult relationship. They're very tense and awkward around each other. Blue wants to improve the relationship and is always seeking out things to do with Stormy, but it usually only makes things worse.
Blue's best friend is Cyclone, the son of Applejack and Soarin. Their cocky personalities go together very well, and they have a sort of competitive friendship. They're always challenging each other to races and contests, much like their mothers. The two are also just bros, and like to help each other out. Blue is also very good friends with Flitterbug, the daughter of Fluttershy and Big Mac and Wednesday Paper, the son of Twilight Sparkle and Quibble Pants.
Blue's marefriend is Aura Shine, the daughter of Moondancer and Comet Tail. He is absolutely head over hooves for her. Blue likes to think of himself as tough, but when he's around Aura he turns into a blushy, stammering mess. Aura finds it endearing.
Blue has enemies too. At least, that's what he calls them when talking to other ponies. Sky High, Dive Bomb and Flametrail, the foals of Spitfire and Firestreak, and Winning Streak, the daughter of Fleetfoot and Night Glider are his arch nemeses. They pretend to hate each other since their parents are in rival flying teams, but they're also sort of friends. Their relationship could be summed up by "I pretend to hate you cause I should but we're actually totally cool".

Note: I'm only going to be doing these full bios for the main cast of my next gen, not every pony because that would take ages.
