Many of these are possible in gameplay, such as showing up Lindow by soloing an Ouroboros. A later mission, known as "Thor's Banquet", has you facing off against four Vajra. Alone. By this point in the game, you can tear through them.
Shio gets one in the ending of the original storyline, hauling the entirety of Nova away to the moon to prevent the Devouring Apocalypse.
In the same vein, Ren, the manifestation of Lindow's God Arc, protecting Lindow from being defeated by Corrosive Hannibal, coupled with something of a Crucified Hero Shot.
The Protagonist gets a few in cutscenes, especially in the Burst storyline. Namely, Dual Wielding his/her and Lindow's God Arc, telling Lindow to not run away from living, punctuating the statement with That's an Order, before double-stabbing Corrosive Hannibal in the mouth, tearing the mouth apart and punching directly into the Core.
Earlier, the Protagonist wields Lindow's God Arc (something that should never be done) after his/her God Arc is broken, in order to defend the Den from an Aragami invasion. Granted, Ren does most of the actual saving.
