It gets worse. Remember how when Kim is sent after Ron, she seems to ignore the Tweebs, and when Drakken orders both girls to catch Rufus, they forget about the other intruders? This implies that the chip takes away all thought processes other than those required to carry out an order... so unless Drakken gives an order, neither girl will MOVE. And they have no way to signal if they're hungry, thirsty, tired, need to go to the bathroom, or anything. If Drakken forgets this, both girls could be forced to slowly waste away, very aware of what's going on, but powerless to stop it.
Which is what he should have done once he managed to stick the chip on Kim (after removing Shego's of course).
It's not "if" he forgets, it's when. We're talking about the guy who had one of his inventions get shorted out because he couldn't be bothered to take Commodore Puddles for a walk....
Another Kim Possible example; remember Warmonga from "Mad Dogs and Aliens" and "Graduation"? Remember the fact that both times she showed up, it was with an arsenal useful for taking over the world practically single-handedly? According to Word Of God, she didn't even have government backing from her home planet there, and when you consider the arsenal included enough walkers to effectively cause a lot of damage to humanity as a whole... what do you think the government packs in comparison? Especially since these are conquistador aliens who travel equipped to take over a world?
Probably not a lot, if anything. Warhok and Warmonga seemed to be treating world conquering as a hobby. Not to amass resources or because Earth was valuable, but because it was fun. So, it probably works on the same concept of asking why doesn't Senor Senior Senior ask for government help with his schemes. They don't really need it and whatever their government can supply is probably woefully inadequate to what the Lowardians already have.
In one episode we see Shego light up one of her fingers with her powers then she touches a villian's mook's forehead with it after which he drops to the floor in a limp heap. Is it possible she gave him a lobotamy?
DNAmy has two of the villains attracted to her (Dr. Drakken and Monkey Fist), at least initially, and even Mr. Barkin is more disturbed by her evil science than by her, personally — all despite her being overweight, bucktoothed and dumpy. Could be interpreted as a feminist message about looking beyond external appearances.
Actually, Barkin finds her annoying from the beginning, but he's reacting to her aggressively clingy personality rather than her appearance. (Also, annoyance seems to be Barkin's default state anyway.)
So, according to the "Animology" personal quiz, Kim and Senor Senior Junior are soul mates. Kim is a globe-hopping Type-A overachiever. Junior is a lazy, narcissistic, Rich Idiot with No Day Job. It doesn't make sense that these two personality types would be soul mates...or does it? Kim is the kind of girl that Junior would have to make a massive self-improvement effort to win over, and Junior is the kind of guy that a girl like Kim would see as a "project" she could make into something better. It's a romantic-comedy staple, really.
In Bonding, Kim and Bonnie are stuck together by a bonding agent at the hip and Ron and Mr. Barkin are stuck together at the shoulder. Why couldn't the problem be solved by changing clothes, which both pairs obviously do multiple times throughout the episode and if the bonding was beyond just their clothes touching, why were they able to change clothes?
I would have to watch the episode again to see if Wade provides an explanation, but the energy effects suggest that the bonding is more magnetic force than adhesion.
