Theodosius is Dylan Grace, son of Zeus and has godlike powers and lightning bolts too. He lives in Mount Olympus, home of the gods.
Since Dylan was the son of Zeus, he could summon lightning, reflect fire, and do many more tricks. He used to practice his powers all the time. When he is furious, his lightning bolts are as powerful as an angry bull.
One day, Zeus told him to help him in saving the Earth from Hades's wrath. So he does what he is told. However, he encounters his archenemy Mortoman. Mortoman had the ability to tame fire and use it to hurt other people. When he shoots fire, the fire produces smoke. Theodosius's weakness is suffocating from smoke, so if Mortoman keeps throwing fireballs, Dylan could die.
