Ava and Marcela can remove any form of obstacle simply by imagining the obstacle gone. They can destroy physical barriers, walls, locks and doors, and can force people to move if these are currently in their way. They can pass through forcefields and can enable others to do the same if they are touching them at the time. They can also remove non-physical barriers and obstacles. This includes barriers preventing the effects of abilities, almost every negating effect, barriers which prevent memories from being recovered and barriers which prevent thought or the realisation of information. However, they find removing non-physical obstacles more difficult and energy consuming than removing physical obstacles.
