Do roaming Pokemon change IVs and personality between encounters?

Jul. 12, 2015

Because I’m too lazy to get a Pokemon that knows Mean Look, False Swipe, and a Sleep-inducing move, I was wondering if I can (in Platinum) use a Scyther to wear down the wild Mesprit’s HP through multiple encounters, and then try my luck at using a Bronzong holding a Quick Claw to Block it and use Hypnosis to put it to sleep so I can catch it. However, I’m worried about what exactly happens if the IV for HP decreases between encounters and I encounter the Mesprit with less than 1 HP. Will I encounter a glitch Pokemon?

I mean come on. Not like a different Mespirit shows up every time. And also experience from a bad natured Raikou.
