I'd like to know, is there a downloadable mod out there to make my DBO character not have an aura, like an android? Something similar to what Tagi did?

Not have an aura like an android? What exactly do you mean?

No,
You would have to do it yourself. Child's Play.

I know what you mean, I was looking up things DBO related on YouTube and I found Tagi's mod videos... He hasn't really given out his files, so I don't know how you would go about applying that mod. Just get into Client Side Modding and try to replicate his mod. It seems hard, but once you get the hang of it, it shouldn't be that hard. Just to prove that I saw the videos, here's the description of one of his WIP Android videos: My DBO character as an Android. Yes, I know Androids do not produce auras. It's the aura is being very fussy, and I was trying to remove it but when I saw how awesome it looked with the aura.... yeah.... Let's just say my generator has an overdrive mode and produces an aura when used. Makes me overheat of course :)

Speaking of which, I think Tagi is actually TrunksX2 here on dbocom. Just PM him and see if he can either show you how to do that or give you a download for that one(You can try to ask him for a download, but I would give him a choice of whether to show you how to do it or give you a download for that, cause I doubt that he'll give you a download link.)

Or just stop being a lazy bum and replicate it yourself.

There is already a thread for modding, please keep it in that thread. Also, a mod like this is childs play. It would take minutes to get rid of auras for your character. You could even turn your character into an android with ease.
