Long video on the history of Gridman, from Hyper Agent Gridman to SSSS.Gridman, SSSS.Dynazenon and everything in between. Gridman grows more and more on the more I think about it. In fact it might be time for a rewatch...
I finally saw Gridman Universe! I had a very good time watching it. I think it might be my favourite of the Gridman animes, and gave me more appreciation of both SSSS series.
