Superman takes this with ease.
Blades are greatly weakened without their Driver, and Aegises are no different. I don't know exactly how much power Pyra would lose because of this, but we could use a fully recovered Malos as a benchmark thanks to him seperating from his Driver long ago.
OP, Pyra is fighting without Rex correct?
Siren's Particle Cannon isn't going to be of much use against Sups since it won't take much effort to swipe Siren out of the sky. The cannon itself is sub light speed, since you can see the light from the beam before the beam itself impacts. Siren's targeting ray does use proper photons and can incinerate a human sized target at a higher output, but that sort of thing won't bother Superman at all.
Pyra does not scale to Zanza. She isn't even in the same universe as him! Pyra can't hope to alter the universe on a universal scale for the simple reason that Pyra can't even slow down the Indol Titan from the side of the World Tree. She needs Poppi to fly her and Rex closer to pull that off (

Pneuma never became the new Architect, as the Architect refers to a person and not a role or title.
Pneuma received authority over the Low Orbit Station after her meeting with the Architect, and she actually lost power when the Architect died, as that was when the Conduit, the source of much of her awesome power left this world (

Pneuma couldn't restore the universe even if the Conduit was still available, as the original experiment required her, Logos, and Ontos, and the latter two are gone at this point (Logos just died and Ontos disappeared in the original experiment). The ring that encircled the Earth that was used during the experiment had just disintegrated as well (

You can even see the damaged but still standing lower levels of the World Tree here (

No reality warping was used after the Final Boss Fight, period.
Where on Earth is this timeline destruction coming from? If you can't provide proof of this claim than your claim will be thrown out.
@Veloxt1r0kore and @UltimateInferno Would you rejoin the debate with these clarifications?
