This is boring i kinda lost interest when i learned of his hatsu it sound really lame i mean why didnt he copy killua hatsu? That is one Hell of ability but then you give him this sad ability he probably will meet canary or some cannon character this is gona be cliche
HolyJoker:He can never reach Killua's power with copying his Hatsu, also what connection does the MC have with Electricity? A Hatsu is an expression of individuality, a copied Hatsu will never be as strong as the original. To the MC it would be about as strong as a tazer if he copied it... probably weaker.
