Double Spiral here is the younger sister of another of my OC's Spiralhoof (who was named pretty literally because their family has a spiral pattern on the bottom of their hooves), who is a very skilled and responsible hypnotherapist. Growing up, Double Spiral hated that her sister Spiralhoof started to develop this talent and kept getting accolades and praise from everybody while DS just got nagging and judgements from her parents. So she started acting out and basically being a bratty teen. But when SH practiced her hypnotism on Double she found it kind of an awakening thing and began to develop a rather unhealthy obsession with learning how to do it. She became a bit of a junkie for using her talent to have other ponies' will bend under her whim. In particular she found a special interest in having them surpress their memories and regress into an infantile state in a blissful release of their worldly responsibilities and troubles so she could baby them, feeling a position of authority and control.
Spiralhoof hates how her sister uses this power but can't really do much to stop her. I'd say while SH is definitely the more practiced and technically knowledgable, able to do hypnosis and hypnotherapy the right way and is very powerful with it, able to change ponies' lives, DS probably has the bigger raw power of her abilities, and is very cunning and creative with its use, particularly in trying to trick other ponies with it, or using post hypnotic suggestions and triggers to remain in control at all times.
----- I've always been shy about sharing art of this pony because she has a bit of a controversial interest, but that's just who she is I guess. She's not the most emotionally healthy X3 But then, I'm not one to judge on that front.
I have been trying to redesign or refresh the designs of my characters across the board and I did Spiralhoof not too long ago, so I thought her bratty younger sister could use a revamp too. There actually had been a WIP featuring her and Fluttershy which I never finished, and am not likely to now. Though I might redraw it and share the WIP. Actually, I think the WIP was just about done anyway XD Sometimes I do that, basically finish soemthing but never feel satisfied and give up on it AT the finish line.
Anyway this one wasn't so arduous, this was a super quick picture and I thought it came out very cute, so, yay! I quite like her new tail design.
