#4 Lethal weapons
If you've seen WWE for any length of time, you'll know that there's no shortage of weapons.
From the steel chair to the kendo stick, to the ladder, there's plenty of things that can leave a mark.
One thing you'll never see again though is a gun.
Shockingly, a firearm was shown in WWE during the Stone Cold-Brian Pillman feud, when the Rattlesnake broke into his former partner's house, leading to Pillman firing the weapon as the screen went black.
Not too long after, another gun (this one a toy) was used by Austin, to embarrass the Chairman Mr. McMahon.
Entertaining moments, but heavily criticized by networks.
With the WWE now focussed on entertaining, family friendly content, a gun is the last thing you should expect to see being wielded by someone like AJ Styles.
