Thank you @Mr Allen J, and @Eklispe for answering in my stead. They brought up really good points that need to be addressed. Your power cannot be in the simple terms of "complete manipulation of all aspects of candy" it has to be more specific. Also I'm gonna assume you're interested Mr Allen J?

The more vague, the more powerful it becomes. You can control sugar as you said before. That may seem weak at first but consider that it is really important to our body. Almost (if not every) part of our body is made up of sugar. I.E. Tear them apart instantly. Let's say your power is governed by the Manton effect though. That means you could stop any villain you know the location of by just willing it. Encase them in razor sharp candy, and battle over. So I need a distance, restrictions on generation time and other specifics.
