As I stated before he will never really overwhelm Nazarick as a whole but at best be able to fight a guardian or a lvl 100 npc from nazarick in a 1v1 fight, however WC items won't be much of use against guardians and Ainz (expect Gargantua and Victim) who have WC items themselves, it is true that just as you said there really isn't anything that is native to the new world that can give a sense of danger and threat to Nazarick, the only people who could would be other players and guilds (which I'm hoping they do exist) I believe I heard that Ainz in the web novel said if there are other powerful guilds who are in the top ranks that could have been transported into the new world, he and Nazarick would be in trouble if they did, I think they even mentioned several names of these guilds in the WN as well.
