In this article, we acquaint with the notion of pointwise quasi bi-slant (PQBS, in brief) submersions in complex geometry. We present the concept of pointwise quasi bi-slant submersions from almost Hermitian manifolds onto Riemannian manifolds as a generalization of pointwise hemi-slant submersions and pointwise semislant submersions and specially, we study such submersions from K¨ahler manifolds onto Riemannian manifolds. We explore the geometry of leaves of distribution which are involved in discussed submersions and furnish with a characterization theorem for pointwise quasi bi-slant submersions with totally umbilical fibers.
