Nobody is saying that girls CAN'T be a fan of all-male Sentai teams, and nobody is saying that boys CAN'T be fans of Sailor Moon. However, the target audience for Sailor Moon is girls, while the target audience for Sentai is both boys AND girls.

You're treating this like there's a perfect balance when there clearly isn't.
Boys have heroes out the wazoo. Sentai features 3 (Sometimes 4) male characters for boys to project themselves onto, Kamen Rider was a solo hero series (Excluding V3 and Tackle, until 2001) only featuring male protagonists (The amount of female Riders in the franchise that appear on screen being 5 (6 including Tackle. There are special and movie exclusive female riders, however). There's also Garo, which is for a bit of an older crowd, but still male exclusive.

Girls have one or two characters in Sentai to project themselves onto, and virtually no presence in Kamen Rider and Garo outside of the supporting cast.
There's also Metal Heroes, which have been dead since the 90's, mind you, but still, like the others, completely male dominated.

No one gets up in a tizzy over Magical Girls' all female cast because it's a girl's best chance to have strong, main characters to relate with that the plot also centers on.
Thankfully, Toei isn't trying to create a divide, because girls still enjoy KR and Sentai, too~

I wouldn't say completely just mostly. Solbrain, Blue SWAT, B-Fighter, and B-Fighter Kabuto all had female members.

I know there were women around, but it was just as much a sausage party as KR :p

Aw, c'mon. At least they weren't movie exclusive characters.

Fair enough~

I wouldn't say Garo doesn't have female heroes. Women may not be allowed to be Makai Knights, but there are a lot of prominent and powerful female Makai Priests throughout the franchise. Rian is generally depicted as Ryuga's partner and equal in most situations, Yuna is considered to be effectively a Knight even if she doesn't have armor, and Jabi is generally viewed as one of the biggest badasses in the entire franchise. We also have two full movies that are focused solely on female characters. I'd rank that as being far more equitable to female characters than anything Sentai, Rider, or Ultraman has done.

Alright, that's fair enough.
I'm just focusing on the henshin hero side of things, rather than the protagonist cast as a whole, since women do play large roles in Kamen Rider as well.

When was the last time superheroes was a male stereotype? We've had Wonder Woman who existed since the 1950's. If anything, that stereotype has been broken by now.

And with your logic, I guess you won't have any problem with a show about an all-male team of chefs to break the stereotype of cooking is for women?

You're right. Sentai is meant for all kids, not just boys. But my point is, one season with all-male team won't hurt.

Exactly! However, we will never have an all-male show ever again. To some people, all-male team is a problem while all-female is perfectly fine. The reason being Zeo said it himself. Sentai would be a good show to try one season of an all-male team out. I mean, they did it with Ghost Busters, why can't Sentai do the same?

If you know of an all-male fighting team that exists. Like groups of 3 or 5. Preferably, still ongoing after 2010, I would love to know what the title of the show is.

Can you site a post of mine that said so?

I personally don't like Kamen Rider's suit design but that sounds like my type of show. Is there a season in Kamen Rider that's a group of men rather than one-man though?

Also, it's true that male superheroes outnumber female superheroes but they are always present in team superhero shows and almost always one of the most significant members in the team. I would count quality over quantity as well.

That's really not the best way to think about Garo. The armor is used just as a finishing move, more often than not. Most of the fighting, male and female, is done out of suit.

Every Rider show after Kuuga has at least two Riders. If you want something with group dynamics, though, I'd go with Ryuki, Blade, or Gaim.
