[x] Blueprints
Well much as you despise the fox and anything to do with him you have to admit that is at least an almost competent scientist and engineer. You must put extra emphasis on the almost part of that earlier sentence though. It would not be due to even entertain the idea that his best designs get even close to to the most basic of your creatures machines after all. Still some of the Fox's ideas had some merit, being able to confound you on at least one occasion even if his actual skill was just bellow your standard of mediocrity.
A quick glance at the blue prints reveal.... huh that is one imaginative fox, an unskilled one but you have to admire his creativity..... though you do so reluctantly.
The first of these contraptions is a transformation system for the next model of his airplane. While he has only created it with the intent of adding a superior flight mode to his current machines looking further into this could lead to plenty of other transformations, even if it is only between 2 forms cheaper transformation would be a very good thing for your lower ranked machines.
Next and perhaps least interesting is a walker mode for his plane, really this is more for the possibility of knowing it's weaknesses when your master encounters it than anything else.
After that is... equpment for Sonic actually, most of it involves ring manipulation and the specific applications given have... limited use for badnicks technological ring manipulation is an interesting concept in of itself and given how often Mobians use rings something that could be valuable in improving the Eggman Empires machines.
Finally you have... hmmmm well this is odd... a fake Chaos Emerald? Pretty much only good for sabatoge outside of actions that would be near impossible... but still it could be an important way to gain an edge in the competition for the real ones given its nearly impossible to tell them appart without prior knowledge.
What do you reaserch?
