We revisit the physical properties of the five brightest supernovae ever, most of them discovered by the ROTSE collaboration and present results on the recently-discovered supernova SN 2008am, an ultra-bright Type-IIn at a red shift of 0.234. We investigate a variety of models based on diffusion or shock interaction for each object. We also present analyses of the peculiar transient events SCP06F6 and a peculiar transient discovered by the ROTSE collaboration that has an unusual spectral and light curve evolution. This event is consistent with neither an AGN outburst, nor a SN, nor a tidal disruption event and its true nature remains a mystery.
