This is Comodo. Now this guy has a lot of backstory so I'll try to explain everything and try now confuse everyone.

Comodo is born in the city known as the Reptilian city. He lived normally without any parents at an orphanage until he learned of his power of Light and Dark energy. The Elders of the Reptilian city met with Comodo and learned of these abilities and wanted Comodo for their own puposes of defeating an evil creature that ewas to come soon as their visions speak of. There was another vision of a great defender who would defeat the evil create with the power of light, and shadow. Comodo was sent back to the orpjhanage and because of his powers he was taunted a ridiculed for them. He ran away from the orphanage and the Elders persuaded Comodo to come with them and they'll use a device to remove Comodo'd powers. (Note: The High Elder did not know anything about this. He was one of the few who would niot think in such a way.) The Elders planned on using a device that would increase Comodo's power instead of get rid of them. The device went out of control and increased Comodo's dark energy powers to extremely high levels changing Comodo into Dark Comodo. Dark Comodo killed off the Scientists and Elders and changed back realizing what he had done and ran. He stopped in an alley but then a new being appeared. It looked Reptilian but was black with red markings over his body. He asked Comodo to help him and he'd repay Comodo in return with a normal life Comodo has always wanted. Comodo agreed and helped the Reptilian only to learn that it was not who he seemed. It was an evil creature named Darkness who was trying to get his hands on all the Reptilian's Dark energy. After absorbing it all Darkness went out and started going on a killing spree through the Reptilian city. Young Comodo tried to fight him but Darkness proved more powerful and more skilled and crippled Comodo to the ground. Darkness then caused an explosion of Dark energy wiping everyone in range of his path out in an instant.
Comodo suddenly reawakens in a lab completely better and wondered where he is. He made it out of the Secret underground lab and saw a new world. He met knew freinds but lost them to Darkness later and he soon grows a grude against Darkness.
