Divine Retribution
Conquistador de pan
I'm not really a manga/anime fan, nor a huge Marvel fan (although I did see Infinity War and Endgame with some friends, and I've seen a few of the other movies over the years as well), but honestly I feel like your comparisons are a little... stretched. I mean, I suppose you can compare nearly any circumstance where it seems like the protagonist is defeated to Infinity War if you wanted to, but Infinity War is not the first movie to do this, only the most recent. Go back almost 40 years to The Empire Strikes Back and we have a movie that opens with the protagonist faction's main base being overrun and ends with the main protagonist getting his ass kicked by one of the main villains.
As for the shocked reaction to the film, I don't think this is wholly unique to Infinity War either. I do think a big part of the reason why it resonated so much with audiences is that most of the MCU series is set on Earth at around our current time period (albeit an Earth inhabited by superheroes and futuristic technology and all sorts of other fantastical nonsense), which makes it much easier to relate with and fully absorb the momentum of the particular event driving the shock factor compared to other movies which are set in more alien or fantastical settings.
I don't think Pokemon could ever really replicate that, at least not fully. Being generally more light-hearted than the MCU series, being set in a much less realistic and relatable environment, as well as being told through the medium of anime/manga rather than live-action film all dampen any "shock value" that similar events might have in Pokemon. It's harder to empathize with characters who exist in a setting completely different to our own under conditions completely different to our own condition.
