Every living thing has an odor. I suppose it's possible to imagine aliens that for some reason never emit particles, but it goes a bit beyond exotic in my opinion. Claws and venom are exotic for humans, but quite mundane compared to excreting small packages of odorless waste.

As I understood it the Perk doesn't make the character completely odorless. They (and their excretions) don't have a strong and/or unpleasant odor. It is still possible to track them by scent just somewhat more difficult. The Perk probably manifests differently based on what it represents though.

Even if it did make one impossibly odorless, it wouldn't stop targets from leaving trackable particulates from or of clothing or grime.

Still much better than perfume, which I would find to be more of an OPH than perk.

The Perfume perk means that the scent your body produces is generally accepted as pleasant. Many flowers and fruits would qualify when statted up as characters.

Simply applying perfume I would agree was an OPH. Those chemicals stink, unlike the Perfume perk which gives you a +1 reaction bonus.

You're risking being found on of those munchkins coming up with annoying 'I treat positive reaction modifiers as annoying, and react to them at an equivalent minues'. If you have Unfazeable (Scent Only), and can ignore the +1 from scents that grant a +1 Reaction against almost everyone, that's a somewhat unusual advantage.

Call me weird, but I dislike the smell of real flowers let alone the almost painful volatiles of synthetic odors. I absolutely loathe the scent of mangoes, and my mom hates bananas.

My social obliviousness grants me partial immunity to many such reaction modifiers. But PCs are normally allowed to react how they wish, not restrained by mere NPC influence rules.

I lived most of my life being able to identify most people by scent from feet away. That overwhelms my social phobia. I've found now after having lost that ability, my social phobia is a little easier to deal with. I might rage over those physically incapable of staying scent neutral.

Re: [SE] Sanitized Metabolism: how useful is +1 in in 'close confines', like 'elevato
 

PCs are still affected by Influencing PCs, and it's still bad RP to routinely ignore the setting and its inhabitants.
Also, it doesn't matter what explanation you use for the partial immunity - GURPS cares about effects, not justifications.

Re: [SE] Sanitized Metabolism: how useful is +1 in in 'close confines', like 'elevato
 

It's a spectrum from choice-less automatons to completely ignoring setting influences. PCs generally sit on one side, while NPCs firmly on the other.

And there are things too fiddly to stat out.
