Hocus was the pilot of Pelican dropship Kilo 023. She assisted in extracting SPARTAN John-117 and Sergeant Major Avery Johnson, along with a squad of liberated Marines from the jungle near Mount Kilimanjaro. Following the Covenant attack on Crow's Nest, Hocus was instrumental in evacuating the rest of the survivors of the attack to the human frigate UNSC Forward Unto Dawn. She participated in numerous ground insertions during the Battle of Installation 00, such as deactivating the shield barriers surrounding the Ark's Control Room, the Citadel.
- On the level Crow's Nest, you can see Hocus' face when she picks up the Marines after the Jump Pack Brutes are killed, by jumping on the front of the Pelican. However, she tends to have a completely different face from time to time, so it is unknown what she really looks like.
- Occasionally, with the IWHBYD skull activated, Sergeant Johnson will say "That was for Hocus."
