Okay, first it's not a "Bionicle" it's a being if you're not being specific. Second, I've never heard of an illusion giving off heat, and I don't know where you got that, but assuming that they did, beings with thermal vision would probably only see a mass of heat around the being. So,if they know its not a Toa of Fire, and they know enough about illusionary properties, then they could figure out that the person is an illusion. It would probably look something like the original aura covered by some illusionary heat, then show as the disguise aura. So, that seems to be correct to me, but who really knows? Greg never really talked about the Illusion power much.
