— Description, Sonic Chronicles: The Dark Brotherhood[1]

Pattern Generator (パターン発生そうち Patān Hassei souchi?) is a quest item in Sonic Chronicles: The Dark Brotherhood.


After the team found their fifth Eggman Device, Tails modified all the devices to create the Pattern Generator. It was unused until the team picked up a strong signal in the western area of Green Hill Zone behind a forcefield. However, Tails matched the frequency of the pattern generator to the frequency of the forcefield, disabling it.


  • The Pattern Generator looks exactly like an Eggman Device.
