American Toku-styled tv series?
 

Besides Power Rangers and VR Troopers of course, It need not be exactly the same, but similar to the least.

For me:

Buffy, The Vampire Slayer
Angel
Stargate SG-1
Agents of SHIELD
Smallville
Arrow
The Flash

These were the ones I remembered at the time

'Nuff said. And yes, I used the German opening because it's just that awesome.

Wow, Mystic Knights of Tir Na Nog looks very cool. A american-toku for sure.

Arrow and Flash totally remind me of American versions of Kamen Rider if they were an 1 Hour long show. Though I figured a lot of American Superheroes are Tokusatsu.
