None of these bots (save for the reject) are seen, but their likely purpose is to revive passengers that have suffered heart attacks. The reject D-FIB appears to have too much charge in her paddles, shown when she shocks a test dummy and sets it on fire. She is freed from the Repair Ward by WALL•E and helps to fight the SECUR-T bots by frying them with her overcharged paddles.
According to the film and the video game, the only word she says (and can say) is "clear".
- D-FIB also appears in the video game where she unlocks security doors (with an image of her) for WALL•E.
- D-FIB is also shown to have a broken arm (due to the way it hangs down).
- D-FIB's paddles are able to electrify other robots. She destroys a SECUR-T robot doing this.
