I imagine that the way Austin turns evil is of course, as you said, thanks to his father neglecting him, and him deciding he HATES spies because of that. But also because Dr. Evil was ALMOST awarded the international man of mystery award at the school. and frankly I think Austin was just one straw away from snapping at that unfortunately bleak time in his life.

The 50s were dull for a groovy guy like him. Squares ruled the earth and were everywhere, he had no parents, and really all he has are his passions for music (as shown by his dorm room decor) and girls... which is kind of super sad??? So I think in this world Dougie would become the next international man of mystery while Austin keeps failing his classes and never wins :( So then he becomes EVIL!!! (dun dun dunnnn)

Austin's main goal as a supervillain is to make everything as groovy and switched-on as possible! Everything has to be pretty and everyone has to be fashionable! No squares allowed EVER!!! He wants to see gogo boots, groovy flowers and swinging shindigs 24/7.... he has not changed much in that department... except for the fact that he's EXTREMELY controlling about it now.

Vanessa and Austin have a very very rocky relationship. Much like Frau Farbissina and Dr. Evil. What's even worse for her is in this world, she isn't allowed to take much initiative and tell Austin when he has outdated views or when she's jealous of his swinger life with other birds. So his violent tendencies (of which he intends to change in the first movie) only increase and get worse and worse. Instead of trying to be a better person, he gets mad at people for not being the way they were in the 60s. That whole thing...

Aaand Dr. Evil, I see him being a pretty humble and goofy hero much like how Austin is shown "not being a good spy" and yet always succeeding. Most of his plans to foil Austin end up working completely on accident. Number 2 is more of a "Q" type figure than a Basil Expositon type, because he's more of a serious guy, and I think it really suits him. The Ministry of Defense would likely be much more serious.

But back to just Dr. Evil himself, I heard him say in an Austin Powers Comedy Central TV special that he has what they call "anti-mojo" because he's such a square and he's so awkward!! so i like to think that anti-mojo works on the Fembots in a different way from the Cross-mojonations. Less like making them explode, and more like shutting them down entirely because of how much anti-mojo there is. It's like sending them off-signals, because he's such a big turn-off.

ALSO. Unlike Austin Powers, Dr. Evil LOVES using gadgets and is fantastic at utilizing them for his missions because he's really good with electronics. This works super well in his favor as a hero!

Dr. Evil probably has many "Bond girls" across his journeys as a spy. But I think they'd be replaced with the girls that he uses as distractions for Austin. Frau Farbissina (of course,) Ivana Humpalot, and Alotta Fagina would be his big 3. And vice versa for Austin. They work more as spies for him, but he's probably still close with them because he still just wants to have a groovy time. I would hope he gets a singing moment with Ming Tea in the same way Dr. Evil gets his rap songs.

Oh and of course... Mini Me. He's probably the most useful companion to Dr. Evil and is possibly a better spy than he is, but we don't talk about that shhhhh.

I don't know if Austin would have something else that happens in place of getting a Mini Me. Maybe he would get some kind of fembot-esque version of himself that captures his own synthetic mojo? (which... I have thoughts on this concept alone... and might make another post about it separately some day.)
