Well Metalder's villain armies was an interesting way to do villains. A pity that the Ordnance Army (the military vehicles) didn't get to do much other than provide back-up and save the occasional puppy (and get blown up by a landmine in the process).

i not see ivived weapons unite into cannon or no side arm holder on belt too

Should they bring back Human Villains for Super Sentai?

Recent Super Sentai Villains has become very stale. They end up becoming a generic doomsday villain with a lazy motivation. I thought it would be very refresh if they bring back the concept of Human Antagonists.

Kamen Rider W, Fourze and even Drive have Human Antagonists and they're more interesting and more threatening than Super Sentai Villains.

Black Cross Army which was First Super Sentai Villain Group have their monster of the week which happens to be a human test subject who turn into a cyborg! Sound like Super Sentai's answer to Kamen Rider's Shocker?

I know Super Sentai is a kid show but I mean Disney Movies have Gaston, Jafar and Dr. Facilier and they're HUMANS and yet they are bad guys! Not all Kid show villain have to be MONSTERS! Humans can be bad guys too!

Enter and Escape weren't that long ago dude.

Neither was Z, although I guess none of those are strictly human.
Not that it matters since they all become monsters in the end.

Could Sentai change of Schcedule someday ?

Super Hero Time has been a thing since the 60s.

dr man is human in bioman

I don't understand.

Nope. It's been a thing since 2003.
