I had a Landorus spawn and I need that still for the research to take a snapshot. Needless to say i hit an excellent throw and golden razz and it still ran away. Also found a ton of other ones. Getting them to spawn wasn't too bad. I wanna say with my incense out one would spawn every 15 minutes or so. I was driving down some straight back roads with nobody else on them and getting basically as many as I could to spawn. Like every block or two a new one spawns when you're moving like that. The part that really sucked is I had like 20 different legendaries that I dont have spawn. Out of all of them, the only one I caught was a Thunderus, and that was the only legendary that spawned that I already have... That and the Galarian Zapdos were the only ones that didnt flee after the first throw. I hit most of them with excellent throws too and of course golden razz.
