7. The Fortress of Solitude
As advanced as Batmans technology may be, it still has one massive disadvantage: it comes from Earth. Superman has an entire Fortress filled with the advanced technology of not only Krypton, but also those hes collected from other worlds and dimensions. If you thought the Batcave was impressive, you still havent seen anything yet, because Supermans playhouse is about as incredible as it gets. And while Superman could easily infiltrate the Batcave, itd be a lot harder for Batman to infiltrate the Fortress of Solitude. After all, this isnt Independence Day and PowerBook cant hack an alien computer. Among the technology Superman has in the Fortress of Solitude are Superman robots that can impersonate him (making it a lot harder for Batman to determine which Superman is the real one when there are dozens of them in different parts of the world at the same time). It also houses a Kryptonian batttlesuit, which can also reduce any potential problems caused by Batmans efforts with Kryptonite. And theres also the matter of the Phantom Zone projector, so if Batman becomes too much of a nuisance, all Superman needs to do is give him a time-out. Batman may have a lot of toys, but so does Superman, and if were going to count all of Batmans toys, then we should grant Superman the same benefit.
