:I Nope. Not gonna regret.
I've decided to give them three love-foals instead of one. Forgive me if the designs looks crappy. <n<;;
Oki.. a lil info for them~

Culgan - he is the eldest foal of King Sombra& Queen Chrysalis, his name is a surname in Irish, meaning "sword"/"thorn". For the past few years, he's been spending his time studying and practicing his place as the heir of his parent's kingdom, so he rarely goes out and hang out with his siblings. Like his father, Culgan is a ruthless& somewhat tyrannical prince, manipulative& malevolent, almost like a foal version of his own dad, except that he has the power to shapeshift like his mother. He only cares for his family and is pretty selfless alot of times. He always argues with Gemmy Peridot for getting in his ways whenever they meet(secretly, they like each other XD). He shares the same power like his parents, changing into shadows, corrupting others, shapeshifting as the other's loved one, the only two additions to this, is he can make a puppet out of not only one pony, but as many as he wants by swiftly grabbing their shadows with his own, and conjuring dark crystals to a designated spot that he desires. Culgan also has holes in his hooves but they are covered in his gleaves. The essence in his eyes are red.

Klaus - the middle-foal of the siblings. Klaus' name means "Victory" in Greek. Klaus isn't much of the warrior among the group, but rather, a very cunning strategist. Whatever plans he has in thought, he would gladly pass it to his father to assure victory. He never fails to make him proud. Klaus is very flamboyant and would often pull off that sinister smile around his lips, not to mention, he HATES getting dirt in his robe and would freak out. But the only power he inherited was his mother shapeshifting skills. And it is of great use as he can sneak into Equestria& Ponyville easily. His eye essence is an unlikely color as it is green, not representing his father's but the color of his mother's power.

Viola - the youngest foal of the siblings. Viola's name means "violet" in Latin. She is the spitting image of their mother. Unlike her brothers, Viola appears to be the only one that has a little kindness to her heart, but she is mostly spoiled and is a narcissist. She has no wings but inherited her father's shadow magic, turning to a huge wave of shadows, it also acts as a transportation for her and summoning dark crystals for combat. King Sombra& Queen Chrysalis gives her the most attention. Her essence is violet like Sombra and her tail is a wavering shadow.

P.S. I'll be making Culgan& Gemmy a couple, but with a very rough beginning& the development of their relationship will really take a huge while for them to actually get along with each other. ;u;
