The man is replaced by someone much more pleasant

The worker seemed to be fine for a second, before his brown hair rapidly changed color in a flash of light and grew longer, turning blonde and curly, while his body seemed to morph. James was stunned, wondering if he had caused this, as the cat simply watched.

Before long, the burly man before him was turned into a stunning blonde woman, wearing clothes that looked less like clothes and more like some kind of country-based fetish gear, complete with a beer in hand, which the now woman quickly handed to James.

"Want anything else, dear? Anything for a cutie like you!", she said in a German accent as she winked, causing James to blush again and look at the cat, confused.

"That is some fairly good work considering you are untrained. All it takes is to focus on what you want and do what you just did. Remember, you won't rely on muscles, and you aren't a man anymore", the cat told him, and James felt he understood. This was but a portion of what he could do to anyone who dared cross him. All he had to do was learn to control it. Easier said than done, but the cat and the library should help.

After a quick turn to wink back at this strange lady, James thought up an idea.

"GO find yourself a job in a local bar or pub, and call my number once you have done that so we can discuss what else you can do for me", he told her, feeling a commanding authority over her, and the woman nodded, quickly taking his phone number. It seemed the magic did more than make the builder a woman in mind and body, it also made her subservient to James.

James nodded at the cat, though it ignored him and simply continued to trot onwards. James had a feeling it would take them quite a while to get to the library at this rate, but decided to just go along with the cat and learn what he could about this new body of his, and its powers. As he walked, he decided to get in a bit of practice, focusing a bit of energy on his fingertips while not thinking of much, just mindlessly walking behind the cat.
