It might be a quasar or an AGN cloud. I'll ask a scientist.

The emission-ine ratios in the spectrum, along with absorption in the higher Balmer lines (H-delta, epsilon...) suggest a galaxy which is not yet post-starburst but is ramping down. Any AGN must be weak by comparison. The oddly-colored feature might be a starburst-driven outflow. If this one were fortunate enough to be a MANGA target for a whole bundle of spectra we'd be able to tell right away.
