When you look at them they are not weak at all:
I wonder if Whittemelia still have Philistine in her side. That guy could eliminate the psionic powers of Quentin Quire easily. And with the power of the Siege Perilous they can teleport easily.
Frankenstein cloned Krakoa in the past ( I wonder if that will be addressed ) and knows how create monsters.
The other two are more irrelevant. Their only “ power “ is their money, but that is always important.
