Dr Strange should have a tier on Monica's level that can close the space-time portal, clearly requiring the same level of energy as opening it. It is an incursion that sucks reality from another universe. Come crash into another universe which happened to dr strange and he closed it as script
scarlet witch can scaling above dr strange
Monica:"She tore a hole in space time"...."Can we fix that"..."in theory you and carol can produce the same amount of energy that was used to open it, ill absorb it, and release it but from inside the tear"
This is such confirmation
captain marvel talk to monica
"wait you want us to blast you with the same amount of power that punch a hole in the fabric of space time"... "if we want to unpunch it.. yeah"
and
this
Even though the reasons for invading are different, the results are the same
America Chavez should also scale to Dar-Benn with both Quantum bands who tore a hole in space-time because she is also able to open holes in the fabric of space-time as well with her multiversal punches
The Art of Multiverse of Madness describes her being able to punch through realities, suggesting that her ability to display such power is related to her punches/physical strength
Her multiversal portals are also described to break apart different planes of reality
And the MCU Timeline book state that she has the power to puncture the barrier between realities which is like Dar-Benn who used the power to punch a hole in the fabric of space-time which hurt Captain Marvel and
Captain Marvel had to use all her power and Kamala use all her power from both bands to generate the power to break space-time
People can argue that her not being able to break glass in the Illuminati is an anti-feat, but that cannot apply to her currently because she did not have control over her powers prior to Wanda capturing her and when she got control it was when Strange tell her to trust her power and her self and she became confident
Her creating the portals or holes in space time should be connected to her AP and striking strength because she uses her strength to create those star-shaped holes in space-time,
as shown in this scene when she punches Wanda, her energy being released from her fists manifests into star - shaped burst which turns into a multiversal portal and crack in space-time and its also shown when she uses that same energy to
break a stone slab in a shape of a star and
her punch created a star shaped crack in the illuminati glass cage thats like the shape of all her portals
So since the power to punch a hole into space time required Kamala to use all her power from both quantum bands that was stated could be used to restart Hala star and required Captain Marvel to also use all her power to generate that same power, America Chavez would scale to Dar-Benn and Kamala with the bands, and Captain Marvel (Low 4-c) because she is also able to display the power to punch holes into the fabric of space-time
scarlet witch should have durability physical (low4-c) she was not harmed by the punches by america chavez had punched her many times with her realised powers
