User:Catalyst/Active and Passive Abilities

Active and Passive Abilities
Peter actively phases though a wall.

All of the abilities shown in Heroes can be classified into two types: those that are active, meaning the user has to make a decision to use his/her ability or not at a given time, and those that are passive, meaning the mechanism that makes the ability work is constantly active and the possessor cannot choose not to use his/her ability.

Active abilities

The following abilities are active in nature. The users of these abilities can decide whether to use their particular ability or not. The users of some of these abilities also have control over the manner in which they use the ability, for example how much electricity to apply or what ability to replicate

Passive Abilities

The following abilities are passive in nature. The users of these abilities cannot choose not to use their particular ability because the mechanism responsible for the ability cannot be turned off (or at the very least have not yet learned to turn said mechanism off). For example, Regenerators like Claire cannot choose to leave their wounds open and gaping, their body automatically and very quickly heals the wound independent of any thinking on the regenerator's part.
