An hour later... Let me explain more detailed [ For simplicity, no scans will be provided to things i believe you already know . However, due note i have MORE than enough scans to prove this. I already found 4-5 scalable High 1-B feats just in Issue 50 . ] :
- With a portion of the Matrix found in Britain, who Merlyn and Roma are far superior to, Meggan and Britain [ during Captain Britain I , Issue 50. They even stated on panel that all alternate universe are on one dimensional level/plane, AKA the fourth dimension, which obviously means the other planes are all the other higher-dimensions, hence High 1-B .YES !!! ] swept through all the infinite planes of reality and removing all the incarnations / versions of the Citadel from it. A similar feat to what Phoenix did, which was puublically recognized as a High 1-B feat by Matt and Ant, our best comic experts here for Marvel [ i trust their word better than anyone elses , and them stating it is High 1-B helped me out with this, because it made this work so much easier ] . We know that the Matrix is High 1-B casually, and obviously now know it [ the Multiverse/Omniverse ] is canonically High 1-B for Britain's Multiverse.
- Merlyn is likely far stronger or at least comparable to Britain's Matrix w/o amp from Matrix [ They even flat out stated on panel he could've fixed the Matrix and every plane of reality with his own power on panel . He even viewed this as nothing more than a game he can manipulate... Yeah. Merlyn's crazy powerful even without the Matrix ] , yet was overpowered by 238 Jaspers. 238 Jaspers was also called a threat to him . Also post-issue 50, he viewed the Multiverse as a tool he can manipulate, meaning he is very casually High 1-B
- Fury and 238 Jasper's fight destroyed Merlyn as collateral damage
- 616 Jaspers who was stated to be stronger than 238 Jaspers [ and a threat to the Omniverse, and being able to destroy it at many points in Britain post issue 50, meaning he is likely High 1-B ] , was revived by a portion of the Chaos Wave. Jaspers described it as an incomprehensible power, meaning it is ludicrously above him.
- Scarlet Witch and Child FR are treated as equals by Cyclops [ Who had Omniscience w/ Phoenix Force , plus saw the entire signatures when they were scanned previously, meaning he outright knows they are comparable ]... And they are at the very least comparable to Jaspers.
Ant wanted me to explain how this makes sense in context for Franklin Richards. Contextually, Franklin being a danger / being able to destroy the Multiverse makes sense based on his portrayal in Britain's comics :
{ They sent the entire Britain Corps after him, threatened to destroy the prime/most important timeline [Earth-616] if his powers weren't sealed right away [ similar scenario to the Omniversal Threat Jaspers , who is treated now as High 1-B rather than 2-A ] , Roma stating he can destroy everything [ When previosuly she viewed every plane in the Omniverse in the Citadel , contradicting Universal levels completely, and heavily implying he can destroy every plane of reality, otherwise Roma stating that makes no sense ] , Madam's Gem cracking by a very casual psychic scream [ the kid did this as a result of crying to himself, meaning he did this feat subconsciously/extremely casually ] from Franklin [ Even going out to say " That is IMPOSSIBLE " ] when it was fine at many High 1-B levels during and after Issue 50 involving the Multiverse within Captain Britain , as it turns out she was there , and sent Eternity and Infinity to examine him to prove how serious they were .}
