Well, if NRG was INSIDE his suit, Lodestar would just magnetize him back and forth or make his suit explode. Afterwards, Lodestar can wield magnetic shields to avoid being hit by NRG's true form, and can regenerate if destroyed. Other than that, I don't think any side can win, except if Lodestar magnitized a large piece of metal and hit NRG with it (again, NRG can go Intangible and doge). So, eventually, no one will win.

But NRG isn't made of fire, so an enclosed fire-proof space wouldn't do much. He could also just get out of his metal suit, go intangible, and get out. The lava wouldn't do anything either if Lodestar threw him in it because he has Pyro Immunity (Heat Resistance). I think that NRG would win this one. :P
