Despair System: Demon Lord of Despair!

Upon waking up, Kyle traveled to an unknown world and turned into an unknown creature! Fortunately, as long as he absorbed the despair, he could continue to evolve! From there was born a most feared existence of the multiverse! He was called the Demon Lord of Despair, Master of Disaster, Destroyer of Worlds, Personification of Despair... He, it will be the most powerful existence in the multiverse. (The MC looks like a Skull kid from Zelda, but he won't have the abilities of a Skull kid. He's someone with a calculating personality, he'll always stay rational when he's in trouble and think about countermeasures, he is also very naughty with his "victims", thus having a sarcastic, playful and calculating personality.) (He will also have powers that can control natural disasters: Earthquakes, Cyclones, Tsunami and many others. He will be an OP protagonist, but not instantly, he will have to work for it, but eventually he will be OP.)
