Kamen Rider Paleo

Kamen Rider Paleo (仮面ライダーパレオ) is a fan series created by Emily Becker. The series tagline is "Can timidity prevent extinction?"

Synopsis
65 million years after the extinction of the dinosaurs, a group of dinosaur-like monsters known as Saurians are planning to do it all over again-but first, they need to at least cleanse some of the planet. To do this, they scan Bone Tickets on dinosaur fossils, before inserting them into people and turning them into Saurians. 20 years ago, one of the victims of this plot was a timid boy named Ryu Kaseki, who lived in a dinosaur museum. He was saved by a mysterious Kamen Rider wielding Bone Tickets of his own, and surprisingly did not explode and suffered no injuries save a small scar on his right cheek.

Now, that same timid young man discovers that he is among the select few who can use Bone Tickets of his own free will, and begins his own battle against extinction as Kamen Rider Paleo. Can this joke of a Rider somehow prevent another meteor from ramming into the earth?
