What you described is not a b*tch, but a creeper/stalker. Viridi is a sarcastic brat who will go to large lengths to embarrass pit and palutena, she is a show off; highly arrogant. She will take any chance to make a smart@$$ comment
I'm fairly sure Tharja also makes pretty catty remarks at everyone who tries to be nice to her too.
Also she abuses her daughter. Like a lot.
Either way sounds like both are pretty much confirmed God tier b*tches. Viridi probably has the edge because she IS a god(dess).
