Seth the Villain?

"Life here is all about Mental Power and Willpower!" Seth added casually while also a pale energy exploded from his body and drowned Dave and him into a perfect sphere.

"Ahhhh!" 

A terrifying scream from Dave was heard and a flash of red lightning rumbled inside the sphere but none of his friends moved forward because their body was still shaken by that pressure.

It felt like it was from a dragon but at the same time it was not. Not only that, there was a sound coming from the red balloon which trapped the beast, it made their body shake. At that moment, few people can have coherent thoughts in those eerie confusing situations.

A streak of red lightning burst out of the pale sphere into the sky, changing the colour of the sky to crimson and it cackled with thunder.

"You shall rest in peace now!" Seth's tired voice said. As he came out of the smoke.
