Super Strength - To be able to lift critically heavy objects with ease, also endurance would be heightened significantly.

Electric type B (non-stealing) - To be able to create electricity out of nothing, heal quickly (as the electric would power up every cell), stun criminals at will, create an emp and have the ability to power anything that requires electric to work, the possibilities would be endless.

Armored Skin - as hard as Diamond but 5x the strength of Titanium. It's completely resistant to all kinds of bullets, explosives, sharp objects, elements etc. It also can take up to 600,000 tons of pressure and would give the ability to charge through walls

Note: I would be pretty slow and my insides wouldn't be armoured if a grenade was to randomly fly into my mouth but I'd be an extremely powerful hero nonetheless. I'd have to pick electricity out of the three as you could do so much more with it than the other two powers though i would prefer all of them to be honest
