  We examine giant gravitons with a worldvolume magnetic flux $q$ in type IIA
pp-wave background and find that they can move away from the origin along $x^4$
direction in target space satisfying $Rx^4=-q$. This nontrivial relation can be
regarded as a complementary relation of the giant graviton on IIA pp-wave and
is shown to be connected to the spacetime uncertainty principle. The giant
graviton is also investigated in a system of N D0-branes as a fuzzy sphere
solution. It is observed that $x^4$ enters into the fuzzy algebra as a
deformation parameter. Such a background dependent Myers effect guarantees that
we again get the crucial relation of our giant graviton. In the paper, we also
find a BIon configuration on the giant graviton in this background.
