Multi-Verse Has A Bad Time

A Random 14 year old boy playing a game in his mobile called Undertale ,while his having an earphones and charger's on , he didn't know that there's a heavy storm with a lot of lightning forming in the clouds , and striking near his house causing the house exploded on black out while the boy die because the lightning traveled on his wires ( ya know what I mean conduction of electricity stuff ) causing his brain toast and he died... unknown too him.... he got fused on someone...or something , as a partner , a Comrade in the battle of Life and Death with the body of 9 year old kid. ( Basically a team death match hunger games too) P : S : I dont own Undertale , Rwby , HSDxD , Death note , Etc only the Characters and the Plot that I've created.
