"Space Squad", from Space Squad: Space Sheriff Gavan VS Tokusou Sentai Dekaranger (2017). Performed by the Clashing Brothers (Gekitotsu Kyodai): Kushida Akira and Yoffy.
I have like no knowledge about Uchuu Keiji Gavan (or Metal Heroes in general, really) but I'm watching the vs Dekaranger film involving that, and well.
Can I just say I really like Mad Gallant's design a lot? Idk masked men are one of my weaknesses-
