he is dominative

"What have you done to me!"

A logical reaction. You expected this.

"I have combined you with the essence of an animal." You casually explain to him.

"What ... why would you do that?"

You paced around the table, explaining your goals to him.

"The world has very few creatures in it, my dear. Every day, many species go extinct, but none are added to it. This is my way or repairing that error. With you, I have given nature a new species. One that is based on the human, the most successful species to date, and I have improved on it."

Your victim was shocked.

"You ... improved me?"

"Yes! With this new body you have enhances speed, greater stamina, improved hearing. You are better then you have ever been before."

You had thought he would rejoice, but instead he was more dismissive

"Good. Now let me go." He ordered.

"My my, so demanding?"

Not happy with your answer, he tried to pull out of the restraints.

"I told you to let me go, so do it."

"Where would you go?" You asked him. "Into a world that has never seen a creature like yourself?"

"I don't care." He said. "I'll find a place."

"Sorry dear, but you will stay in this room."

"Are you going to keep me tied up as well?"

With a wave of your hands, the straps unfastened themselves. The man quickly jumped up and lunged for you. You were not quick enough to react and found yourself captured by him.

You instead used your magic to summon a strong gust of wind and blew her off of yourself.

"If anyone is to be ordered around, it shan't be me, little kitty."

He looked very angry at you, but chose not to attack you again. He knew he couldn't stand up against your magic.

Like you warned him, he did not attempt to leave the room. Not at first, at least. He was probably eager to escape, but knew he couldn't do anything while you were around.

You were happy, your experiment was a huge success. However now, you had a tiger-boy to deal with.
