We present a multi-wavelength (X-ray, optical and radio) spatial and spectral analysis of the extragalactic superbubble N7793-S26. Prior observations and analysis of this source had revealed extended emission spanning nearly 400 parsecs at all three wavelength domains: the extended morphology of this object suggests a superbubble classification, prompting the argument that N7793-S26 is actually a microquasar. We investigate the microquasar interpretation of this source based on analysis of its spatial and spectral properties and compare N7793-S26 to another known extragalactic superbubble located in the Local Group Galaxy IC 10. We investigate the scenario that the soft X-ray sources seen at the northern and southern edges of N7793-S26 are actually supernova remnants and that the central hard X-ray source is an X-ray binary serendipitously located to give the appearance of a central engine with two jets. This scenario will be presented and discussed.
