Agent 9 (Prime 8) is a cancelled game that was being developed by Blue Tongue Entertainment and Backbone Entertainment as a spin-off of the Spyro the Dragon franchise. it featured Agent 9 as the main playable protagonist.
Blue Tongue Version
Sometime in 2003 / 2004, Vivendi Universal wanted to use Agent 9 to be the protagonist of his own platform adventure game, out from the Spyro world.
Vivendi asked Blue Tongue Entertainment to create the initial concept for this new project, in which Agent 9 became a James-Bond-alike spy, but after a series of focus groups with kids, they had to redesign the character to make him more “cool” to appeal more to the right audience. Agent 9 became Prime 8, with a more “hip” look and gameplay that should have been similar to the Ratchet & Clank series. Sadly, even after this redesign, something went wrong during the development and Prime 8 was never released.
Another pitch was proposed to Backbone Entertainment. Backbone created a series of concept designs more true to the original character (as seen in Spyro the Dragon). In the end there were at least 2 different “Agent 9″ projects, but we can speculate that Vivendi Universal did not like any of them and these games were never finished.

Reason it was cancelled
It was turning into something like ratchet and clank and vivendi universal didn't enjoy the idea
