Changeling the Beast Lacrima (Teen Titans X Fairy Tail)

Not Enough...

Beast Boy looked on in awe as the clash between Raven and her demonic father Trigon went on. Flashes of energy were causing the very air to spark as she pushed him back. But suddenly... It didn't work. Trigon stood strong against the blasts.

"Foolish child. You may have caught me off guard, but that is all your pathetic magic has done. Now I shall finish you!" The demon roared, the shockwave from his attack sending the five Teen Titans crashing into buildings.

"Raven's power... It isn't enough?" He asked as he coughed from all the dust his impact had kicked up, pulling himself out of the crater he had formed.

"She took him by surprise, but she needs help. Let me take control and help her." A dark voice growled in the changeling's head, which he was shocked to hear. He knew what it was, even if he had never heard the voice in his life. The Beast.

"I... Won't let you take control!" He whispered under his breath so the others wouldn't hear him. The Beast had never spoken to him like this, always trying to wrestle control from him by force. So what was its deal all of a sudden?

"She'll die without us. Without me. Can you let that happen? All you have to do is let me in, and she will survive." He hated to admit his confliction. He recalled how the Beast had helped defend Raven both against Adonis and at the beginning of the End against Slade and his fire spirits. No matter what it wanted from him, it seemed to have Raven's best interests at heart. And with a demonic mirror reminding him of what happened with Terra, he couldn't let Raven die as well.

"Do it. Don't make me regret this..." He closed his eyes and took a deep breath. This could either end really good or really really REALLY bad.

"You won't. It is time for us to unleash our full power for the first time!" The manifestation of his predatory instincts let out a roar inside his head, which for some reason his mouth began making as well as he felt himself shifting, his bones snapping and aligning as he took on a form he hadn't yet become.

If his roar had been loud before, it was deafening as he finished his transformation, a massive Emerald Dragon that barely had room to maneuver even with wings compact against its back. Unlike Beast Boy's other transformations, with pale white eyes, the Emerald Dragon had glowing green eyes with black slits.

"Finally, it appears there is a true challenge!" Trigon was the first to get over the expected shock, raising his huge club at the reptilian monster. The two titanic opponents let out roars as Demon and Beast charged each other, the other four Titans looking in shock as the ground quaked.

The Dragon roared again, this time so loud and powerful it sent out a shockwave, identical to Trigon's own roar that sent the all powerful demon backwards into the Titan's Tower, which had been his throne and was now a pile of rubble beneath a groaning behemoth.

"Such a surprise coming from one of my daughter's foolish friends..." He focused magic over his crimson clawed hands, the energy sparking as it came into contact with air. "Relegant bestiam!" Trigon shouted, and sparks danced over Beast Boy's scaled hide until they finally faded.

The dragon raised the ridge above its eye as if it were an eyebrow, before crouching low and jumping with as much force as it could muster in its four legs, launching it into the air and allowing it to extend its wings, flying across the bay at great speeds towards Trigon, who managed to scramble to his feet and attempted to smash his club into the charging dragon's head.

Unfortunately for the demon, Beast Boy met it head on. Literally, he headbutted the fuck outta that club.

Trigon's four red eyes widened in shock as he realized just how powerful this being was. But its power was unrefined, raw. It couldn't keep this up, and then he could kill it once it was exhausted. He smirked, revealing his pointed teeth as the dragon whipped around to follow through with its inertia, smacking Trigon with its long tail, only for it to be caught.
