Notes

• At one time, writers Joe Pokaski and Aron Coleite said that Peter only has access to one power at a time. However, Peter has clearly demonstrated his proficiency at using multiple powers simultaneously on more than one occasion. Indeed, he was able to do so on one of his first attempts at using an ability independently.
