Has anyone ever caught a raid boss on their last ball?

Only once that I remember with out question.

I've wondered the same

Happend to me. My first Lugia.

Yes its possible. What is even more interesting is if someone has ever seen a different animation than 1 shake during their last ball when the Pokemon escapes.

i caught a tyranitar on my last ball before, not legendaries tho...

I've caught Gengar on the last ball before.

Today. Moltres in the last ball (without bonus, only curve) after 9 great or excellent curveballs

Caught a Moltres on last ball today, 100% sure because I remember someone posting about this just like 2 days ago, so I thought about that specifically today when it happened.

Question to all that caught it on the last ball: was it a critical catch or a regular catch?

From my city I only know of confirmed last ball catches with a critical hit
