Goliath SD/9 is a robot in TimeSplitters Future Perfect that can be unlocked for arcade mode. In story mode, you meet huge versions of it twice. The first time is in the Machine Wars level, where you take control of it at the end to shoot down ships to clear a path for you. The second time is in the Something To Crow About level where you fight it as a boss halfway through.
