OC's:
Name: CasmFire
Age: 12
Bio: CasmFire earned her name pretty wildly. (Religious content) Her mother died when she was pregnant with her and Satan allowed her to be born, but CasmFire was too pure to belong in Hell (the place of course) and was thrown out from a chasm of fire. Due to the fact she was pure, they kicked the 'H' out of her name, cause you know...Hell starts with H. CasmFire is part cat, part human. She has blonde hair and blue eyes and she wears a pink tube top with a red skirt and white combat boots. Sometimes she wears a brown sweatshirt with a periwinkle T-shirt and dark blue jeans. CasmFire lives in Sarasaland but likes to visit Bowser Castle for her dream to become a minion and serve Bowser, mostly so she can be Lemmy's girlfriend, but now she is and stuffs.

Name: Cynthia
Age: 11 (she's only a little bit younger than CasmFire, but it still results in her being a year younger)
Bio: Cynthia is part dog part human with pink hair, pine eyes, a cyan T-shirt with darker jeans and black sneakers. Cynthia is CasmFire's best friend and commonly accompanies her on her visits to Bowser Castle and developed a crush on Iggy Koopa. She lives with CasmFire actually and wants to rule over Mushoom Kingdom.

Name: Dawnshine
Age: 11
Bio: Dawnshine is part wolf part human and is best friends with Cynthia and CasmFire. She wears a pale yellow dress with same-colored slip-ons and she has bright blond hair. Dawnshine has a light obsession with Bowser Jr. with various products sold around her hometown. Dawnshine wants to become best friends with Bowser Jr., but hopes that she could find a way that they could date due to the fact that Bowser Jr. is extremly young.

I've personalized the Koopalings on occasions.
The birth order goes like this when personalized:
Ludwig - accented genius, finds Iggy annoying
Iggy - enthusiastic insane scientist, bullied by Roy and constantly argues with Ludwig
Lemmy - slightly depressed who spends a lot of his time on the computer, a brony :D
Wendy O. - girl stereotype but not as bratty as commonly made
Roy - bully, loves to stuff Larry in the toilet
Morton - talks a lot (nothing changed)
Larry - smart alek, show-off, mischeif maker
Bowser Jr. - Larry's companion most of the time, acts like an everyday baby Koopa but really has a lot of brains on Larry knows about

CasmFire represents ME, of course. (I Have A SERIOUSLY awkward crush on Lemmy :3)
Cynthia represents my friend. (I made her take a quiz and adjusted some stuff)
Dawnshine represents my OTHER friend. (Same with Cynth.)

Name: Marie Koopara
Age: 12
Bio: Marie is Wendy's enemy. She is conceited and you know...has extreme stereotypical mean girl qualities. Yus, I'm so original.

Name: Tag
Age: 13
Bio: CasmFire's half-brother. He is like a IRL stick figure with sharp crimson horns. He has two other forms: Spirit and Mega. Spirit makes him transparent and gives him abilities of so-thought-out ghosts. Mega allow Tag to smash things easily and surrounds him with firey power. Whenever people see him, they see it as a bad thing because the horns first make them think, "Satan," which kind of conects how he and CasmFire are related. :}

Name: Sonny Thunder Blaze
Age: Unknown
Bio: I wrote teh story about her. But, she's a Pikachu who got inflamed with power by some evil people (lol, nothing better to call 'em ;D) and knows every move Pokemon know. It was said that she once had a crush on Bowser, even MARRIED him, but soon broke up because the Koopalings (in her mind) hated her. Sonny is self-conscious but doesn't show it.

Note: I'm not sure why, but RD gets on my nerves. Oops, let me rephrase. Her FANS get on my nerves. So, if anything bad happens to anypony, it's RD. Meaning my demented mind's cooking up some schemes, girl...or guy.
