The genie can only give you a superpower (with required secondary powers). Can't wish for things like Omnipotence or Big Guns, because they're beyond his power.
What do you wish for?
Heck yeah! I got this. I'd wish for the ability to summon electric guitars from lightning!

I think it means any secondary powers required for the primary one to work. For example, Wolverine's mutant healing to go with his adamantium claws.
Well, strictly speaking, you don't need Wolverine's healing specifically, but yeah, having your bones covered in unbreakable metal would probably kill you on its own. That sorta thing.
