Squirrel Girl wins this....simple math.
Squirrel Girl = automatically involved in all KMC threads
since Squirrel Girl, whom I will refer to as SG from now on, defeated Thanos, and knowing the following -
Thanos >>> SS
Thanos >>> Firelord
SS > Firelord
SS + Firelord <<< Thanos
So one can conclude that Squirrel Girl also >>> SS + Firelord.
Knowing SG >>> SS+Firelord
and that BP Armbar > SS
and that Spidey Jobber Aura > Firelord
In addition, Since SS > Firelord, therefore
BP armbar > Spidey jobber aura
Thanos >>> SS, but since BP armbar > SS
we conclude THanos only >> BP armbar
SG > Thanos >> BP armbar > Spidey jobber aura
so naturally, SG > BP armbar + Spidey jobber aura
anyways, my drunken mathematics can only deduce that SG pwns all here and there's just no doubt about it - its air-tight, just like Homer's proof to Flanders that god didn't exist.
