[ Quoting the top comments from the Envision Invasion Eradication page, which has the same boss targets ]

The demonic commanders cannot spawn in any of the invasions, they do have specific ones. But they spawn in multiple invasions. There are 6 invasions total: Naigtal, Sangua, Val, Bonich, Cen'gar and Aurinor.

The following have now been found in all six invasions:
Mazgoroth
Gorgoloth
Dread Knight Zak'gal
Fel Lord Kaz'ral
Harbinger Drel'nathar
Dreadbringer Valus
Malphazel
Vogrethar the Defiled
Baldrazar

And the remaining have been found in all invasions except Sangua:
Flamecaller Vazrah
Flameweaver Verathix
Vel'thrak the Punisher
Flamebringer Az'rothel

A tip for anyone that is missing 1 or 2 of the bosses. If you do an invasion point (that has a chance at the boss you want) and get to stage 3, if you see that it is not a boss you need, you can run out of the entrance and zone back in. You will be be put into a new scenario with another chance at getting the boss. Whenever you find the boss you need, attack and boom done. This is what I did for my last one, though took 29 tries for Vezrah to show lol.
