Unless MC has a power source with extremely high voltage, it will be difficult for him to create a effect like lightning, lightning occurs when electricity is released and burns the air, and because air is a poor conductor of electricity, MC would need an enormous amount of power to do this. Additionally, I don't think MC should use lightning bolts to attack, because due to air's poor conductivity, when he discharges electricity through the air, a lot of energy will be lost as heat and light, significantly reducing the electrical attack's damage. Of course, this technique could also be used to blind his enemies, but MC can do that by learning to mimic bioluminescence ability.

If MC want more upgrade, he can learn about nanotechnology and create nanomachine to make him become a perfect cyborg like T-3000
