>>58048324 (OP)Well, thread's still up, so let's give it a go.
I guess I'd be sleepdrunk enough to not notice until standing in front of the mirror in the bathroom, so that would be a nice surprise to start with. Once the initial panic has waned a bit, try to get a feeling of this new body, try not to scorch anything with Aura at this point. Try using a phone (hope you lot aren't using face ID or fingerprints for that) so I could contact my brother in an attempt to explain what has happened. With some luck, I don't scare anyone else away right then. I'd attempt going through the normal notions of daily life and work after a few days in that case.
Even if some other people would get TF'ed at the same time, things would get pretty awkward from that point on, even if you are still able to do almost everything your former human self could. Of course, you'd have a shitton of furries lusting after your Lucario self, the bigger issue would be some shady agencies who would do not very nice things to get that precious Aura of yours. So you'd probably be on edge all the time.
On a somewhat more positive note, you'd be able to read minds of people up close, which would either help you a lot sensing danger or would just drive you utterly insane, no in between.
On the bright side, you got some really nifty Aura powers and a good arsenal of moves to fight with, so that balances it out as long you keep yourself sane enough. I'd think I would keep myself sane enough, while at the same time being overly obsessed with getting a Mega Stone as soon as possible. Because let's be honest, that extra power is too good to ignore, and it looks even better.
And perhaps I'd meet another formerly human Anon down the line, which most likely would be less awkward than being the only former human in a social group of humans.
