Garrus-9

Garrus-9 is an Autobot penitentiary in the IDW continuity portion of the Generation 1 continuity family.

A comprehensive detention and rehabilitation facility, Garrus-9 is decidedly more humane than comparable Decepticon prisons. Under its warden Fortress Maximus, the penitentiary houses the disembodied sparks of those arrested under the Tyrest Accord by warrant officers such as Ultra Magnus.

Those incarcerated include:

• Arcee - Classified as "Threat Level 9"
• Bludgeon
• Longtooth
• Repugnus
