I was wondering, Absol can sense natural disasters like earthquakes or tidal waves, but can they sense other type of disasters. Like if a person is a walking natural disaster or has really bad luck?

I’m afraid so, anonymous. Absol’s ability to detect any kind of bad luck is not limited to natural disasters. It’s just that the worse the disaster is, the more clearly an absol can see it. However, it can foretell practically anything that’s considered unlucky for anyone surrounding it, from death to its owner losing half of their favorite pair of socks. So if you own an absol and happen to be particularly unlucky, your absol will be able to pick up on every last bit of bad luck that is fated to come your way.
