@pyrofn: Pretty sure MMH kept a entire race from dying. Manhunter has mindraped the Spectre twice, mind controlled the entire J.L.A, controlled multiversal artifacts like the Wargolog, and so on.
Raven is an Empath and also has telepathy.
Maxima defeated two planetary telepaths. Brainiac power alone went to cosmic level and tp assault did nothing to Maxima and she kept her own thoughts. Pretty sure Jean, Emma, and Psylocke don't equal cosmic level tp. She was able to oneshot Brainiac with telepathy who is still a high level planetary telepathy with out cosmic tp.
Not only that Maxima has more raw power then any of the trio... created a intergalactic psi road from her planet to Earth still had enough power to fight Superman, Starbreaker, who would stomp the trio alone feed off the energy of Maxima planet to regain his complete power and defeated Maxima. While weak from Starbreaker, Maxima was able to use her tk and keep her planet together. Not to mention Maxima can absorb energy just like Jean but unlike Jean it does not have to be psi.
They don't have the TP to get passed her resistance nor any other power to put her down. They can easily get speed blitz by Maxima, Diana, Cheetah, Donna, and more.
