Body insertion is the ability to insert a person into someone else's body.
- A future Peter Petrelli is the only character known to have this ability.
Future Peter claims to have hid his present self inside Jesse Murphy, who claims to be Peter Petrelli during Sylar's attack on Level 5. Future Peter said that he was keeping his present day self safe by doing this and that he planned to undo this action when it was safe. Future Peter later retrieved his younger self from Jesse's body by physically pushing him out of Jesse's body. Present day Peter's entire body and mind then appeared from inside Jesse.
Jesse's appearance did not change while Peter was inside his body and Peter maintained full control of Jesse's actions while he has resided within him. Peter did not appear capable of using his own abilities (e.g. - was frozen in time by Future Peter), but was able to use those of the body he was inhabiting.
After Peter is removed from him, Jesse seems to be aware of Peter's presence, or lack thereof.
