Nintendo

I'm glad you asked, Horsecook. Well, my take is this:

Pokemon depicts the fictional Pokemon as friends of the protagonist who submit willingly to their control after "capturing" them. It's in line with humans keeping pet animals in captivity, since they also have no say in the matter but eventually come to depend on the human. The problem of course is the "blood sport," which is most analogous to dog or cock fighting. That said, this is Nintendo's kid-friendly fictionalized world, and the depictions in this show no blood or injury, and only that Pokemon get tired and "faint."

But in the end, and most importantly, Pokemon aren't real. Whatever is in the Pokemon game does doesn't violate any animal or human rights, even if Pokemon were depicted as blood-drinking monsters who derived their power from sacrificing cherubic Christian children to Mammon at a blood moon pentagram altar, clad head-to-paw in white robes weeks after Labor Day. I think that's a vital distinction.

On the other hand, ICE's social videos are about treating real humans with equal or less respect than animals. It is meant to normalize removing their human rights including procedural and substantive due process, and parading them to viewers as little more than sub-human vermin (a favorite word of Trump and Stephen Miller for those picked up by ICE), and criminals (usually without any legally reliable basis).

So TLDR: Pokemon anthropomorphizes fictional animals and treats them mostly kindly, with debatable exceptions. ICE dehumanizes real people and treats them as subhuman. I think Nintendo has a pretty good argument that (as this is not intentionally parody of Pokemon, but an ICE recruitment ad) that their brand/market is being damaged.
