[Starman]

So, a pretty rough idea I've been working on recently. Moving forward, we'll call it 'Kamen Rider Generations'.

In Neon City (I like super futuristic settings, lol), there was an evil organization of cultists, psychics, and dark artists, who were obsessed with bringing their Abyssal Lords into our world and were the cause of a lot of missing people's cases. Fortunately, when the police failed, there was one hero who could put them in their place. A man on a motorcycle who wore a mask; Kamen Rider Star.

Fast forward to modern day. It's been 25 years and Star is now 45, working as a mechanic. When a string of missing cases happen again and mysterious rumors start spreading around, Star becomes suspicious before eventually finding out that the cult is not only operational again, but have actually succeeded...somewhat.

They haven't fully brought their Masters into their world, but they were able to get a sample of their DNA and have been injecting it into their mooks, thus creating their legion of Abyssmen, who's goal is to grow stronger by consuming the Life Energy of Humans, grow strong enough to Evolve, and lay an egg to give birth to a perfected Abyssal Lord, who will be their new lord and master and probably take over, if not destroy, the world.

Kamen Rider Star's suit would have some grafted on scars, perhaps a tattered scarf or cape, with some noticeable patch jobs. Star has seen some stuff and he's considerably older. But it's not about age, it's experience. And would fight with a myriad of special moves. A few examples at the top of my head would be...

Heavy Hurricane: A clothesline/lariat where he grabs someone with his forearm and spins them in place, creating a literal hurricane before he slams his target on the ground, with anyone sucked into his vortex would hit the floor. His suit would open up small vents to increase his speed and generate the wind.

Nitro Knuckle: Jets would pop up from his right arm, propelling him forward before he gives a right hook to someone.

And, of course, the iconic Rider Kick: Where his kicking leg would be supercharged with electricity before he does the iconic move.

His suit would have all sorts of built-in augmentations to perform these moves, being a suped-up version of the Showa-Era Riders and all of their moves and gadgets.

Meanwhile, while Star is dealing with cultists, he's also helping out his College-Aged Niece, who's living with him for some reason or another. At first glance, she's just a side character for Star to interact with, but unbeknownst to him for a few episodes, she would actually be moonlighting as a masked vigilante herself: Kamen Rider Heart!

Heart's parents would've been sacrificed to this cult before the show and that is how they would've gotten the DNA for the Abyssmen. Being there when it happened, she saw the first hand the incantations and rituals that they had performed to get as close as they did and decided to use the dark arts against them and created the Wicked Hearts, little heart-shaped trinkets that, when inserted into her belt, will activate some kind of magical power. (This is one of those details I'm not 100% sure on, cause I can't think of some kind of "Collectible Power-Up" to give Heart or what kind of theme they'd have and the 'Wicked Hearts' are kind of loosely defined and, well, I don't like 'em. It's just the best I came up with.)

And, finally, the Abyssmen would have a fish-theme to them, effectively sea-life twisted into monstrous forms, a poor imitation of the Abyss Lords they were mutated from. (You know, basically Lovecraftian Horrors WITHOUT risking copyright law, lol.)
