I'm already a bit dubious about human psychics, much less human "aura wielders"
atleast with psychics, I know it's atleast theoretically possible, we're descendant from psychic types, and while human bioenergy levels are very low, it's atleast plausible. but humans usin a force we haven't even properly documented, my first instinct is to assume they're idiots, or atleast take it with a whole truckload a salt
I'll admit I don't think it's impossible, our understanding of the world has been thrown on its head several times, darwinian evolution, plate tectonics, bioenergy itself, and if we weren't tryina prove ourselves wrong we wouldn't be doin science
but I'm not about to throw the hand to anecdotal evidence and mysteries with other, simpler explanations, not just yet
I'll admit I don't know much about mega evolution, so I couldn't tell you jack or shit about the validity of that claim, but from what little I know, I'd hypothesize the extendin markings are from the huge influx of energy brought by mega evolution, like how it radically changes a pokemon's body otherwise
as for lucario not bein able to read bioenergy or psychic energy that far, we know other pokemon can do that, and it should be noted that lucario are incredibly sensitive and it takes alot to develop that level of reach at all. and as for readin emotions without psychic typing, there's several that can do that too, like a number of fairy types, and that's part of what the psychic energy is proposed to explain. I mean psychic activity, not specifically psychic type
I am open to be proven wrong, if it exists or if it doesn't we can't really say. it's not impossible, but I don't think right now there's enough solid evidence to treat it as somethin substantial.
serin mysteries we can't explain is how we learn new things in science, and if that day comes for aura I'll concede, but until we get real, solid documentation on its existence and its effects, more than random people or the quirks of one species, I'm not about to hold my breath
