We consider a D-brane type state which shares the characteristic of the
recently found giant magnon of Hofman and Maldacena. More specifically we find
a bound state of giant graviton (D3-brane) and giant magnon (F-string), which
has exactly the same anomalous dimension as that of the giant magnon. It is
described by the D3-brane with electric flux which is topologically a S3
elongated by the electric flux. The angular momentum and energy are infinite,
but split sensibly into two parts -- the infinite part precisely the same as
that of the giant magnon and the finite part which can be identified as the
contribution from the giant graviton. We discuss that the corresponding dual
gauge theory operator is not a simple chain type but rather admixture of the
(sub-)determinant and chain types.Comment: 18 pages, 5 figures; v2 references added; v3 a reference added; v4
