All KR and SS duos/twins

When i say duos, not 1 time duos. Duos who started around the same time, and are ALWAYS together, rarely separating, form a kick-ass team, fight together in combat ALL THE TIME and are basically twins. Name all the ones you know from Kamen Rider and Super Sentai.
PS: they have to be suited heroes.
->If i say you guys debate, that means that one of the two is a main hero, and the other doesn't appear often, but they are obviously a duo.
Please, if someone already mentioned one, don't repeat it.

Kamen Rider:
Kick Hopper and Punch Hopper
Todoroki and Zanki? (You guys debate on this one)

Super Sentai:
Go-On Gold and Go-On Silver
Kabuto Raijer and Kuwagata Raijer
Deka Break and Deka Bright? (You guys debate on this...)

Alright go and make thing list bigger

SS: Go-on Black and Go-on Green

Alternate Zero and KR Tiger?

I'd say Yuto and Deneb were definitely a good duo, plus, you can't forget about Kamen Rider Ichigo and Nigo, the original rider duo

Also, Black Bison and Green Sai from Liveman.

kabuto & sasword were/are evenly matched most of the time ...

Red Hawk & Black Condor from JetMan?

FiveBlack and FiveYellow
They're basically twins...

Kamen Rider Stronger and Denpa Ningen Tackle.
