HOTW- Electric Wave Tackle

 From KamenRiderFandom- Yuriko Misaki was a newly finished cyborg ready to serve the evil Black Satan organization but she was still inactive. Everything changed as her soon-to-be best friend Shigeru Jo entered the room she was staying in trying to find a way out of Black Satan's secret lair, found her on an operating table and awakens her. After some talk he convinced her to come with him and together with a good friend to many Kamen Riders, Tobee Tachibana they fought the Black Satan as Kamen Rider Stronger and the Electronic Wave Humanoid Tackle for quite some time. Over time she fell in love with him. But sadly Yuriko gave her life to defeat the evil Dr. Kate in order to save Shigeru from being poisoned. This would forever haunt him and pushed him to undergo surgery in order attain the even more powerful (and dangerous) Charge Up form.

I love Tackle, and still think she should be the first female Kamen Rider.  It was said in Kamen Rider Spirits why she didn't want the title, but come on.   She deserved it, especially if they gave Riderman the title after he "died" the first time.  Yuriko Misaki was portrayed by the late Kyoko Okada (岡田 京子, Okada Kyōko).  She did not put up with much nonsense from Shigeru Jo (城 茂, Jō Shigeru) is the main protagonist of Kamen Rider Stronger.  Like at all.  Another reason she was great.
