The Cop Speeder is evidently based on a police car. It composed of a rounded white floating transporter-like car piloted by a Kiki. In Sonic Adventure, its face is blocked with a black cover. However, the face of the Badnik is opened in Sonic Generations.
The E-10 Cop Speeders' first appearance was in Sonic Adventure and later its remake, Sonic Adventure DX: Director's Cut. In this game, they only appeared in Speed Highway for all playable characters. They are either positioned on the edges of the areas where they remain in standby mode until the player approaches, upon where they activate, or are just patrolling areas until the player arrives.
Cop Speeders are rather difficult enemies. Once spotting the player, they start driving around haphazardly in arcs, which makes them hard to get a lock on, with sirens flashing and blaring while trying to hit the player from above, Sometimes, not even the Homing Attack can catch up with them.
In the console/PC version of Sonic Generations, Cop Speeders appear in both Acts of Speed Highway. In gameplay, their movements are stabler than in Sonic Adventure and they are easier to take out. However, their still-random movements make it unwise to use the Boost against them.
In Speed Highway Act 1, Cop Speeders mostly appear by themselves. In Speed Highway Act 2 though, they tend to show up in never-ending groups. Additionally, a statue of a Cop Speeder will appear in the secret Statue Room if the player enters the right code.
