#some of those seemed like natural Collector powers but i assume they worked b/c they were sort of working 'around' king?

Since the Collector was able to trap King in a nightmare vision and then flat out said "my powers don't work on King" like five minutes later, the dreamscape can't be a Collector-specific power. It must be something else (maybe something other people could potentially learn like how Belos learned the draining spell) which the Collector supplemented with their puppet stuff. I think it's really fun that the Collector has a bunch of super overpowered inherent magic because of what they are and then on top of that he also knows a bunch of other kinds of magic that he can use to get around Titan immunity (at least in the case of a baby Titan who still lacks power and skill) or teach to other people. I love this overpowered little brat.
