|The Fall of Nemesis: Clash of the Kaijujin|
The Fall of Nemesis: Clash of the Kaijujin (often abbreviated as KCO1) is the first official CKC original monster game, which is set to be released exclusively for the PC.
"The Kaijujin have a new champion - Nemesis - and they have organized a tournament to see how well she fares against a collection of Earth's mightiest kaiju! (Plus a few uninvited guests…) competition will be fierce both on and off the field - and ultimately Nemesis will fall!"

- Even though technically The Fall of Nemesis: Clash of the Kaijujin is the second Colossal Kaiju Combat game (the first being Kaijuland Battles), it is officially labeled as "KCO1" by Sunstone Games.
- Originally, there was a reward in the Colossal Kaiju Combat OUYA Kickstarter in which the person who pledged $10,000 would have their original monster be the 12th monster in The Fall of Nemesis: Clash of the Kaijujin. Unfortunately, since the kickstarter failed, the 12th monster was scrapped.
