I think I may have a way to fix the food shortage worldwide and make out like a bandit at the same time.
Problem: Food is scarce because America's breadbasket has turned into BnL's omni-dump. With AUTO reigning supreme over the garbage and the government quarantining the area, that's unlikely to change if we leave it alone.
Solution:
1) Recruit Inquinator
2) Send him on the "One Man's Trash" quest with a team of our hero units
3) Kick AUTO's ass into next week and free the humans and robots aboard the Axiom
4) Invent a Compost-inator, a device capable of turning any type of garbage into nutrient-rich compost, and use it on some of the trash mountains
5) Hire the Axiom residents to spread the compost around and create farmland
6) Install some air purifiers like the ones we have in Doofania and some Rain-inators (yes, that's an actual, canon thing) to make sure the crops have enough resources
7) Start growing crops and put Inquinator in charge of our "Filthy Farms" (because we can't turn all of the trash into compost, it'll go bad, so we need lots in storage)
8) Talk with the government about a cover-up plan (they gave us a government contract to solve the food problem, which we succeeded in splendidly)
9) Reap the benefits by going public; the government gets food, one less King, and some much needed PR, while we get control of the Midwest and the food supply. Not to mention all of this will force a lot of the other kings to take us seriously, lowering the DC for diplomatic relations (except for Doom, he'll hate us all the more for this, but it's Judge Doom, who cares?) and getting us in especially good graces with Xanatos since we worked with the government. These combined factors will probably make the idea of an alliance all the more appealing to Shego and Xanatos. Also, we can start our own garbage collection company so we can take in more garbage for compost
