Suggestion is the ability to force others to obey one's spoken imperatives.
- Eden McCain naturally possessed this ability. (Seven Minutes to Midnight)
- Kelly possesses this ability. (The Civilian)
- Damen Peak possesses this ability. (Damen Peak)
- A man in Seattle has been robbing people by verbally persuading them to give him their money. (Save the Cheerleader, Destroy the World)
Eden's power of persuasion requires speech (so, it would not work if she were gagged), and presumably requires the affected individual to understand the spoken commands and be able to act on them.
Eden's suggestions do not compel instant obedience. She sometimes has to repeat commands before her victims obey (Six Months Ago), and the exact wording of the command may affect its success (Sylar appeared to resist Eden's rather complex set of commands at the end of Fallout). However, when strongly focused, the true limits of the power may extend to outright killing of the victim through pure power of persuasion (Life Before Eden).
This power appears to require active concentration: not every suggestion Eden makes has an unnaturally persuasive effect; she has to intentionally use the power.
Damen Peak can influence people's actions with his voice. He used his ability on his wife to persuade her to leave the house with him. When actively using his ability, his eyes glow blue, as do the eyes of his victims.
- In an interview, Aron Coleite and Joe Pokaski explain that, although unusual vocal effects were used for both Sylar (Distractions) and Peter Petrelli (Unexpected), both were for "coolness factor", and were not an indication that either was using persuasion. They later reiterated the point in reference to Sylar's voice in .07%.
- This power is also known as "suggestion".
- Persuasion appears to be an aspect of telepathy. While Eden can compel others with verbal commands, Matt Parkman has shown that he has the ability to coerce others by implanting thoughts. Telepaths are also able to accomplish this verbally.
