Combustionbending is firebending from your mind...
Physcic Bloodbending is bloodbending from your mind...
What would be physcic bending techniques for Air and Earthbending?
(I don't count spiritual projection for air because it's not really 'bending' anything)
Esper=extrasensory perception=another way to refer to psychics.
Saitama, not only that, but in the flashback, Noatak also moved his head, but Yakone explicitly said he "mastered psychic bloodbending." Yakone would also move to look at whomever he was bloodbending, & also did weird face movements.
This is why I think it's not that you're strictly bending with NO movement, but that you're using SO LITTLE you might as well be. And bending with your hands is still stronger.
