Future Jin stood over the defeated remains of Thanatos like the rightful victor of war. His feet were firmly lodged over the black cloth while he stared down unimpressed. Defeating Thanatos was said to be an impossible task. That was how the Goddess of Destiny had designed the Demon of Death.
Thanatos was immortal, with an incorporeal form and a power that could instantly kill all his foes. Even if every living creature on Earth banded together to deal with this threat, they would have been annihilated with no room to despair.
Yet, when Jin summoned his future self to possess his body, Thanatos was dispatched like one would play with a kid or a puppy. There was just no comparison between the two.
It was laughable to think that Thanatos even stood a chance after watching Jin's majestic display. All the time, the man didn't even unleash his full power. He played with Thanatos, and when he eventually got bored, future Jin annihilated the Demon with a single spell.
