Doctor Madden as seen in Sonic Chronicles: The Dark Brotherhood.

Doctor Madden (ドクター・マッデン Dokutā Madden?) is a scientist in Sonic Chronicles: The Dark Brotherhood.


Doctor Madden traveled to Green Hill Zone in order to investigate the strange, hostile behavior of the animals in the area. Once there, he found three signal projectors emitting a signal, which caused the animals to behave strangely. However, when he attempted to shut them down, the animals turned on him, hence why he is only shown in terrible medical condition. After Sonic and his friends shut down the three projectors, which are guarded by Raptor Hawks, Madden rewards the player with Cure All Spray and Rusty Hydraulics.
