Lol I know almost all of you voted ThunderlanexCloudchaser but I had this idea for a ThunderDust kid so I cheated and made one for each ship

From left to right, top to bottom:
Comet Blaze
Son of Thunderlane and Lightning Dust*
Blaze takes after his mother; being a daredevil doing crazy flying tricks, very competitive, and flirts by playfully teasing. He isn't afraid to take risks and is quite brash. He is rivals with Ri, and thinks Storm is hot which causes Ri to dislike him even more. Storm thinks he's a reckless idiot- which he is.
*Thunderlane and Lightning Dust met at a bar. Long story short Lightning got pregnant, but didn't feel ready to be a mother. She left the baby colt at his father's doorstep, and died from a reckless crash a few days later. Thunderlane had no choice but to keep his accidental son, and through that matured a lot. A year or two later he marries Cloudchaser.

Silverwind
Son of Thunderlane and Cloudchaser
Silver is very chill and relaxed, enjoying the small things in life. He loves hanging out at the beach and will often create nice breezes for Ponyville in the summer. He is more mature than his older half-brother, and he has a crush on Smart Cookie.

Dolphin Dancer
Daughter of Sapphire Shores and Hoity Toity
Dolphin Dancer is mainly bubbly but sassy when it's needed. She is a very graceful dancer. Since Sapphire Shores became Sweetie Belle's mentor as a teen, the two are close and so Dolphin used to babysit Trim and Zelda a lot. They look up to her like an older sister now.
Decided not to use DeeDee since I have enough characters.

Magic Trick
Daughter of Trixie Lulamoon and Prince Blueblood 
Trick was raised very carefully and turned out a very well mannered filly, as her parents didn't want her to be as arrogant as they once were. The two once conceited-now-royals did everything in their power to keep a good image and be accepted, but not all ponies believed their acts of charity and smiles; saying it was all a charade so they'd have good publicity. So as Trick got older and started to see all the judgmental ponies that looked down upon her family, she grew bitter. Now she is just what her parents tried to prevent her from becoming; a snobby, bitter, and arrogant princess. Her talent is actually not in magic particularly, but lies in tricking others with distractions-like a non-unicorn magician would. She despises Midnight as she thinks of her as 'little miss perfect', has a fat crush on Prince Romeo, and hides a soft spot for foals who are judged based on their parents' mistakes.

Treble 'Trouble' Tune
Daughter of Octavia and Royal Riff
Although her parents are refined musicians with class to spare, Treble turned out a rebel due to their strict rules and manners. She loves nothing more than to sneak out and go to Strobe Light's raves and party hard. She's a flirt but a heartbreaker, thus her nickname. Her CM is actually a bass clef since both her parents' CM's are treble clefs.

Strobe Light
Son of Vinyl Scratch and Neon Lights
Strobe is pretty much a copy of his parents; sarcastic, cool, and loves dub step. However he is not a musician like them, rather he manages raves and gets his party on with his best friend Treble.

Dragonfly
Daughter of Silver Spoon and Snails
Even though she and Page play the bullies figures, they are actually not snobbish, stereotypical bullies like their mothers once were. Dragonfly is quite sincere and a bit nerdy, loving to collect and observe bugs. She is only rude to Trim and her friends because of the love triangle with the kids. Dragonfly likes Page, but Page likes Trim. So Dragonfly makes fun of Trim and friends to make herself look better.

Pageant Prize
Son of Diamond Tiara and Snips
Even though Page and Dragonfly play the bullies figures, they are actually not snobbish, stereotypical bullies like their mothers once were. Page is actually a bit quiet and generous. He is occasionally bullied himself by older colts because his mother forces him to do pageants even though he's a boy. He teases Trim because he has a crush on her and apparently that's how little boys show their affection xD He also just kinda goes along with whatever Dragonfly says so if she teases someone else he will too.
