By the way---on that third panel, Mindmistress is hooking her feet underneath a part of the flooring that had been partially uprooted in the battle---but still connected to the it gives her a "foundation". Otherwise, as an observant reader noted, no matter how strong she was, she would only have her body mass to push "down" with....and the tank, being more massive, nothing would happen except Mindmistress would do a pull-up. Instead, by "hooking" her legs around that bit of flooring, she has the mass of the foundation of the building to pull down with.
