Chairman Drek was going to sound very different at one point in early development, according to an unused audio file in an early demo.Another scrapped weapon was the Mackerel 3000, a gadget that would replace Ratchet's wrench with a giant fish, but it was scrapped because they couldn't get it to animate well. Some of the most notable ones include a drill weapon called the Revolverator that was difficult to program and was simply not enjoyable to use (but it makes a cameo in-game as a prop used by the miner on Hoven), and a Giganto Ray and Shrink-O-Ray weapon that only appeared in promo images for the game some of these scrapped weapons even managed to sneak onto the cover of the game. They designed at least 70 weapons and gadgets before scaling it down to thirty, so there were some scrapped weapons that didn't make the cut in the original game.Ted was aggravated about it at first, but realized the look worked better when somebody applied the suggested redesign anyway. Ratchet was originally going to be brown, but a representative from Sony Japan told Ted Price that they didn't think his look worked and suggested he be yellow and have stripes on his ears.

Clank was originally supposed to be three floating spheres, each with an individual personality, but they ultimately decided it would be too difficult to keep the personalities from competing for attention (not to mention they looked aesthetically terrible on Ratchet) so they condensed them all into Clank. Ratchet went through several different early designs, one of which was even shorter than he ended up in his final design, and one that was more cat-like.
