In Sonic Adventure, Station Square Police are deployed to intercept Chaos. They arrive at the scene, taking positions. The commander orders them to fire, but their weapons prove useless. The commander then orders all personnel to retreat, while giving cover fire. Luckily, Sonic arrived and disposed of Chaos. They later appear at points in the story, causing roadblocks or ceasing access to the train station. The police seen fighting Chaos resemble G.U.N, and could be associated with them.
- It could be that the Station Square Police are members of the group G.U.N.
- They also look very similar to the G.U.N. soldiers in Shadow the Hedgehog.
- When the Station Square Police fire bullets at Chaos, they bounce off him. This is impossible considering bullets would just shoot through Chaos and sink to his feet unless he was made out of a jelly-like substance.
