an emperor scorpion

You had decided to combine him with an emperor scorpion. You had the man strapped naked onto a table. He was a little difficult at first, but after you cast a dizzy spell on him he was much easier to handle. You are expecting him to grow a tail, so for safety precautions you had him facing down. The ritual could begin.

You collected two scorpion claws and a tail and placed them on the man's back. You placed your hand over it and summoned your magic. This put an ethereal glow over your subject. The man started to become worried and asked "What are you doing?"

You chose to ignore him and continue the spell.

"Stop it." He said softly.

You continued to ignore him and persisted the spell.

The man began breathing heavily. He felt something was happening to him.

"Stop it! Stop it, please! Somebody, help me!" He tried to say. He was too dizzy to resist at all and was completely at your mercy.

Finally the preparations were complete. The merging could begin.

The man's back became like liquid, allowing the tail and claws to disappear into it. While they were absorbed by the man's body, he started to change.

First he started to grow a tail. It kept growing longer and arched upward like any regular scorpions tail. Black segments grew on his tail, including a stinger at the end.

His hands and feet also grew black bony segments covering them.

There were no further changes. You were a little disappointed, you had expected more. But no matter, he would be a great specimen to study on.

Once that was done, the merging was complete. You ended the spell and retracted your hand.

You had turned the man into a scorpion-boy.
