M87 is one of over a dozen misaligned AGNs revealed by Fermi Large Area Telescope in gamma-rays above E>100 MeV. In this paper, I will first provide a census of the misaligned AGN counts, discussing their observational and physical properties (FR type, luminosity, variability, origin of gamma-ray emission, etc.) in comparison with other gamma-ray AGNs, typically blazars. I will then focus mainly on M87, which we have monitored with VLBI for the last seven years using the EVN, VLBA, and VERA. I will present a study on the core and HST-1 light curves, and the kinematics within HST-1, with a focus on the ejection of new superluminal components, and a comparison with the Fermi light curve.
