He was just flying away! People kept doing that today! Kami sighed, as he became electricity, and appeared in front of the villain. If there was one thing his power was good for, it was preventing people from walking away from him. He'd have to establish a rule that people don't walk away from him. It was annoying. Finishing his contemplation, Kmi held up his hand, and it crackled with electric power, causing a humming sound. "Don't turn your back on me, or you'll live to regret it." That was good. He liked that effect, with the little speech. Very intimidating.
"You joined a fight, my friend, and you sided with a bad guy. That makes you a bad guy. Or is that too complex for you to understand?" Kami was still annoyed at this guy for walking away. He was also eager to test out his powers, and didn't like this opportunity slipping away.
