Metroid and its stalker enemies

The stalker enemies seems like a love it or hate it thing, and personally I'm really hoping they stay. That said, I'm interested to know how would you people refine it to better integrate it to the world?

Fusion had SA-X and her moments are really good and effective "jumpscares" for first playthroughs but the drawback is that they are indeed scripted and short

Zero Mission's endgame has space pirates following a vulnerable samus and once spotted, they will pursue her and they can be persistent. Much more dynamic but you have a ton of leeway as they can be stunned and they're not as lethal as SA-X

Samus Returns has Diggernaut which technically is a stalker enemy but not really since it's only a one time chase sequence. But it served the foundation for MS in dread.

Dread has EMMIs, they are confined to one area and trigger a high speed cat and mouse chase. Personally I find it thrilling and nails the dread part of the game, but their one-hit kill and their major recurring presence throughout the game is pretty divisive

Personally, a mix of dread's and zero mission's would be the most ideal. I want dynamic encounters without confining them to a single area. I want the threat of being pursued but also having the chance to fight it off. Like for example, the local fauna would have 1 or 2 special stalker animals that can stalk like the EMMIs but aren't as oppressive like the space pirates, just to give an idea.

I'd love to hear yours!
