I believe mining confirms Mew has a 100% Catch Rate and 0% Flee rate, not sure how the other legends work.these little challenges are getting a little addictive as it was a challenge for me to get a streak of up to 3 or 5 greats in a row, ended up tossing them at a nidorino. I noticed I could never get a nice/great/excellent on a castform so I had to avoid those certain pokemon. While I haven't had a bonus pokemon run on me, I had a few that broke out of pokeballs at least once so I'm wondering if there's any risk when eventually facing a legendary or even a Mew that it could run hopefully not.
Mew is probably because they expect people to want more of them than most Legends since it has the giant movepool customization "appeal"
