RX~J0136.9-3510 is an unusual Narrow-line Seyfert 1 galaxy (NLS1). We have detected extended (~12" or ~54 kpc) soft X-ray emission in the ROSAT HRI image, accounting for 20% of the total emission. We have also detected a highly blueshifted (7.6 keV in the source frame) Fe K\alpha line in the ASCA SIS spectrum. This is the first detection of such a highly blueshifted line in a NLS1. Near-IR and FIR studies indicate the presence of a possible starburst component in this NLS1. Physical models of the accretion and/or outflow and the evolution of this NLS1 are discussed in the context of these results.
