There's more to Zeras, Lord Zero's assistant.
Let's give you an origin of how Zeras met Zero.
Zeras was shocked to see the three Gods destroy Lord Meriz in front of his and other Draken's eyes. Years had passed and he grew into a teenager. He kept training and training.
The more he trained, the stronger he felt. "I feel the power flowing through me," he said. "I'm going to kill those Gods once and for all!". He charged up his energy and destroyed the last punching bag in his room.
When he grew older and saw Lord Zero take the throne as the new ruler of Drakenaka, Zeras stepped up to him in front of a big crowd of Drakens.
"Who are you?" Lord Zero said.
"My name is Zeras. I want to help you get revenge on Meriz's death."
The whole crowd laughed at him.
"You think you're powerful enough to stop those Gods?" Zero said. "Prove it to me and the whole crowd of Drake-"
Zeras jumped up so high and crushed the ground using his fist when he landed. The ground started cracking and everyone screamed and stepped away from the crack. Zeras showed no fear.
"When you die Lord Zero, I will become the next ruler of Drakenaka. I know you're old and you're still charging up your energy, but I want to help you destroy those Gods and get the Claw Relics!"
Everyone behind him looks in fear at Zeras. Zeras turns around and looks at the crowd.
"Do all of you want to be my punching bag?"
All of them back away in fear and screams. Lord Zero smiles evilly at Zeras.
"You're in, Zeras." Lord Zero said.
They both shake hands and head inside the castle where they set up their plans on landing on Sariju to defeat the Gods and claim the eight Claw Relics. Zeras trained with Lord Zero, by using the Drakenoids he created as a punching bag for training.
Zeras is considered powerful than Lord Zero himself. But once Zero fully recovers soon... he will be more powerful and more stronger until he runs out of energy.
