Roar of the Thunderbeast
"Raiju. It's your turn."
Grey thunderclouds began converging above above the courtyard, nearly blocking the moonlight. The Lunatic spun around, confused, wondering what the hell was going on. The Ghost Hunters and Ghosts, however, were too busy fighting one another to notice.
That is, until this happened.
"ROOAAAR!"
With an ear-splitting bellow, Raiju leaped out of Finn's body in a shimmer of light, unleashing a powerful shockwave of energy all around it as it landed on the concrete ground and sent fractures outbounds.
BOOM!
The ground shook as several bolts of powerful blue lightning struck down from above, zapping all of the Phantoms and Wraiths to death instantly. Even the ones that were invisible could not escape their fate, and were reduced to nothing but ashes in the mere blink of an eye.
