Fixten

In a world where summoners wield the power to call forth vampires, elves, angels, demons, and all humanoid creatures from across the realms, Nathan found himself unable to summon beings except from beasts. 

However, those beasts are not ordinary beasts. They are divine beings who once stood at the same level, if not higher, than the legendary creatures the world ever knew. 

Casting his gaze to the left, Nathan sees numerous summoners accompanied by the likes of demon kings, archangels, vampire progenitors, and other legendary beings. Turning to the right, a massive army of alien symbiotes is waiting to attack. 

There was no fear in his eyes, because standing on his left is a majestic wolf who managed to kill a god, the legendary eight-headed serpent coils on his right, above him is the bird who is glowing like the sun, and behind him is a dragon that once gnawed the roots of the world tree. 

“Let the war begin.”

Summoners War: Only I Summoned Divine Beasts

Nidhogg was completely dominating the entire battle.

The Ent tried to form a layer of wood to stop Nidhogg, but the latter simply released his breath, burning the wood down almost instantly. After that, he flew toward him and slapped the Ent.

The Ent didn't plan to lose easily either. He turned as big as Nidhogg and grasped Nidhogg's hands with branches.

Nidhogg took a huge bite of the Ent's arm and ripped it apart before spitting it out. "This is disgusting. The Yggdrasil at least had some taste."

Once one arm was gone, Nidhogg grabbed the Ent's body as his claws this time released the chaos side.

The agony from his own body burning was reflected in the branch's action. They were swirling around as though they were going to wither away, but those withering parts were ripped apart by the other hand, removing the fire from his body.
