Bruce Nolan VS Bill Cipher (Bruce Almighty VS Gravity Falls)

Idk, maybe Bruce?

Ye

Yeah, because he is literally at God-power level, which is technically boundless, but Bill would probably put up a good fight, as he is strong enough to destroy entire dimensions and warp reality. He would win mid-diff at least, low-diff at max

By "him," I mean Bruce Nolan.

Well yes Bruce would cook Bill

Yes, in short, he would be cooked to "Well Done."

Nah he'd be Medium Rare

Connections
Both were originally normal beings until something happened to give them godly powers (Bruce was granted God's powers by God Himself and Bill went into the third dimension, destroying his dimension and making him a god)
Both don't use their powers that effectively (Bruce does dumb yet effective things and Bill toys around with his victims)
Possibly More
Battle Name: Weirdmageddon 4: Somewhere in Buffalo
In this scenario, Bill starts Weirdmageddon in Buffalo, New York, where Bruce lives. Bruce will then be granted God's powers by God Himself to fight Bill.
Will the almighty reporter banish Bill, or will he be overpowered by the God of weirdness?

Bruce Nolan will probably manipulate Bill and make him say a bunch of gibberish before erasing him from existence with his mind. Yes, the Almighty reporter (if he even knew how to) would create the 2nd dimension again and banish Bill to it.

But Bill actually wanted to go home
If anything Bruce would trap Bill in a nightmarish version of the second dimension where Bill dies over and over and over and over infinitely

Is that why he wanted to destroy the third dimension? I'm not familiar with Gravity Falls lore...

No he wanted to destroy it because yes
