The weapon fires a Holo-pod unit which has a hologram of Gastro, the Mothership's janitor, who downloaded his consciousness in a holographic unit when the Mothership was destroyed, just like Orthopox. His unit automatically shoots plasma bolts at Crypto's enemies and also project energy bombs for more damage.
- It is unknown what happened to Gastro after the extinction of the Blisk. It can be presumed, he was put into stasis by Pox and forgotten.
- Gastro is one of the only weapons, other than the Zap-O-Matic, that is effective at doing sufficient damage to the Blisk.
- In concept art from the early production days of Destroy All Humans! shows the prototype-Orthopox bares a heavy resemblance to Gastroenteritis.
