Basically it makes it easier to talk to someone. You see something you want you're most likely going to interact with it.
This could just as easily be Enhanced Persuasion with the descriptor being that the target sees someone or something that they most desire or trust; I'd suggest reading the Persuasion skill description. Apply it to both Persuasion and Deception and you basically have something similar to a very powerful Attractive Advantage.* You could buy up the skill(s) to hit caps (PL+10), so a PL10 Desire Daemon could increase Persuasion and Deception to +20. This would allow routine Persuasion checks with 4 degrees of success, improving opponents' attitudes by 2 steps, possibly better with good rolls or multiple actions. The high Deception would allow Bluffing (believing anything they say), Feinting and Tricking (distracting them in combat), and Disguise (making the target believe the demon is their beloved) as a DC30, making it very difficult to resist for most PCs and practically impossible for more mundane NPCs. Again, check the skill descriptions, as I'm pretty sure this would cover everything you described if not more.
EDIT - by default, this effect could be maintained on multiple people simultaneously if bought like this, so one opponent might see the daemon as a statuesque black man and another might see the same demon as a small asian girl. If you made it so it only worked on one person at a time, that would probably be worth a Flaw. Also, if multiple opponents see different things and compare notes, they might get a bonus to resist the effect.
*Incidentally, an NPC with this power shouldn't actually shouldn't have the Attractive Advantage since it's based on only being effective on roughly half of the people you encounter, but your power would logically work on everyone equally well.
