I gave the first 4 episodes of Go Go Loser Ranger a try
The author is on the record as saying he wanted a "The Boys" version of Super Sentai. Effectively, the "Dragon Keepers" (aka: this universe's version of "The Power Rangers") are an incredibly corrupt group of assholes (akin to "The Seven" from The Boys). The Dragon Keepers beat the aliens just one year into the war by killing all of their bosses. The only remnants of the aliens are the "Dusters", a group of Putty-patrol like mooks. The "Dusters" / mooks have disguises and regeneration, but otherwise are just cannon fodder.
The Dragon Keepers have decided that the best role for the Dusters to play is for them to "invade" at the stadium arena every Sunday, putting on a giant show to a cheering crowd. That way, the Dragon Keepers can continuously improve their reputation as worldwide heroes who saved the world. This has clearly become a commercial event where lots of civilians regularly attend for some excitement every week.
The main character, "Fighter D", has grown tired of this charade, and has begun to fight back.
-------
Alas, Fighter D is stupid, weak, and pathetic. While he's good at putting on disguises to look like various humans he meets, "Fighter D" is quite ignorant of the human world. Fortunately, the first two humans he meets are Yumeko and Hibiki, two people who are seemingly interested in helping this hapless mook enact revenge against the Dragon Keepers.
The main benefit of these three is that the Dragon Keepers are incredibly arrogant and don't see any of the "Dusters" as a threat. Red Keeper makes a point to say that Red Keeper literally can't tell these mooks apart, nor does he have any plans to look at them more closely and figure out their differences.
-----------
The worldbuilding and inversions of Super Sentai tropes is handled pretty well. It seems like each "Color" is closer to a gang as opposed to a unified team or unified force. Red Keeper is the leader of the Reds. Blue Keeper is the leader of the Blues. Etc. etc. At the bottom are the "Colorless", basically interns who haven't chosen a color yet.
I don't think the various colors are quite at war with each other yet, but... Red vs Blue vs Yellow (etc. etc.) are quite self-serving. Red Keeper himself is a very "Homelander" like figure who rules his Red Battalion with an iron-fist, an entire group of people who believe that might-makes-right, with Red Keeper the strongest of them all. I'm expecting that Yumeko's plan is to somehow pit the Keepers against each other or otherwise cause the colors to fight against each other, because as this show continues its clear that there's some pent-up anger between groups.
Furthermore: its clear to me that "Fighter D" is just not strong enough for any kind of direct confrontation. "Fighter D" is barely strong enough to take on a regular human (and Yumeko has proven that she's far stronger than Fighter D... let alone the Henshin/Transformed Dragon Keepers who sit atop the food chain).
Still, "Fighter D" has an incredible shapeshifting / disguise ability. With more knowledge of the politics between the groups and how these forces are laid out, its not so hard to imagine them succeeding in their plan of chaos and revenge. Its a difficult and high-risk road ahead, but... who doesn't like a good underdog story?
Forget a direct fight with these guys. Even normal humans totally outclass Fighter D. The transformed Dragon Keepers are on a superhero-level of strength.
