Poison and Ponies...
Poison and Ponies...
By talonhunter
What would you do if the only way to save yourself was to change. Not just a decision, but fundamentally change your very being. Such are the choices of Ranma Saotome and Twilight Sparkle.
All was quiet in Canterlot castle...except for the pacing of hoofs in the room of Equestria's newest princess. "How did I get into this?" The red and black maned sable alicorn mare moaned to the heavens. How was she to know the soup was a transport spell to a different world. Well that wasn't exactly true. The soup, when not prepared properly, was a poison that could cause changes...and those changes for her left her susceptible to the magics of her new form and she was transported by a spell of her own making to the one place she could heal. Too bad it had taken away her human form...and her masculinity. But here she was. Accepted, loved, cared for. Her responsibilities as protector of the realm as well as her newest title of princess left the battle pony at loose ends. Still, she wished Celestia wouldn't make such a big deal about her newest princess. But the one thing she could say in all honesty was Ranma Saotome never backed away from a challenge or shirked her responsibility...unlike a certain panda she trained under. Had it been that long ago? Time seemed to pass here differently then it did where she came from....
Twilight Sparkle was on her way back from her home in Ponyville when she got the news. Her time away from the castle in Equestria had been cut short due to another Alicorn having been crowned. Now, no longer the newest princess of Equestria...the novelty having worn off long ago, she was surprised to hear the newest Alicorn was actually older then her. Could she be a new element of harmony like Cadence, separate but integral with Equestria? Rumor had it the newest princess wasn't at all feminine, in fact she was suppose to be a battle mare. Unsure what to feel about those facts, she moved on to other facts and information she had. The pictures of her battle prowess had Her feeling butterflies in her belly. This Ranma Saotome made her feel giddy and coltish. What was she thinking. This was a new princess..." Get your self under control, Twilight Sparkle, or you'll crash like a young pegasi." Twilight Sparkle lands near the gates lost in thought, barely noting those who greet her return. 'Why does this feel so...' She is distracted by the sight of the new Alicorn. Her sable coat and bright red and black mane and tail sparkle in the mid day sun. The last thought the elemental Mage Alicorn had were 'Oh my' before causing a clamor from her passing out.
