My point was that Monarch releasing universe-busting energy upon his death does not cap his power to universe-level, and his ability to match SBP with the amp he possessed leads me to believe Monarch operates above baseline universal. Especially if we take his boasts towards the Monitors (i.e. that all 52 monitors couldn”t crack his armor) or the Monitors’ abject fear of Monarch.
There”s also amped SBP’s feats against Mxy to consider. Even if Mxy was vastly weakened, he would have to be weakened to a literal infinite extent for SBP to not be beyond universal from it, given Mxy can destroy a universe as easily as you or I can put on socks.
Add the haxx that Monarch wields, and I can easily see him solo’ing DBS with low-Multiversal power + haxx.
