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.
• So far, only Linda, Peter, and Sylar (and their future counterparts) have demonstrated the ability to access multiple powers. Of course, they are the only characters who have multiple powers.
