This remake of the 1970s Japanese TV series Shiruba Kamen (Silver Mask) and Supa Robotto Reddo Baron (Super Robot Red Baron) takes the heroes from both - an armored bionic superhero and a red giant robot - and has them fight aliens to save Earth and prevent the extinction of mankind.
In the year 2050, life as we know it is gone on Earth. No, not just the COVID-19 we're dealing with now, but the Killgis have used their giant robot Black Baron to terraform our planet and make it just like their planet. The Kasuga family travel back in time with the plans to make their own robot, a device that shows them who is an alien, psychic powers and the Silver Mask suit, which is soon given to a scientist's pit fighting brother.
If you're a fan of the Senkosha heroes like The Samurai, Moonlight Mask, Kousoku Esper and Yusei Oji, you'll be happy when Goro Kirishima, the hero of Iron King, shows up at the end to warn that the Shiranui are coming to Earth. Here's to more crossover films like this, as I had a blast watching it.
I like that the aliens chose Earth because we were going to destroy ourselves anyway. This is the kind of mindless - I say that in a good way - giant robot punching magic that Japan does so well.
