|“||BloodMonkey was the name of a character in the game before it became a Metroid game. That’s why the "monkey upper" etc room names in Tallon IV.||„|
Several pieces of artwork in Prime's Concept Gallery use "monkey" to describe rooms and architecture. Design notes for several rooms refer to them as floors of the "monkey lair", and repeated references are made to "monkey hole[s]". This artwork was evidently used to create the rooms in the final game, as mapping data refers to Totem Access as "Monkey_Hallway", Burn Dome as "Monkey Lower", Dynamo as "Monkey_Shaft", and Ruined Gallery as "MonkeyUpper". The Burn Dome seems particularly connected to BloodMonkey, as the Incinerator Drone fought within the room is referred to as "monkeyFlamethrower" in the game's animation data, and its theme music is named "rui_monkeylower" in the game's files.
Role in Metroid PrimeEdit
It seems likely that Blood Monkey was intended to be recycled from Metaforce, and used as a boss in Prime. The concept art shows multiple floors of the "monkey lair", one of which has a large pit that is "open to below". The intent may have been for Samus to pursue BloodMonkey from the lowest floor of its lair to the top, taking care not to fall down to the bottom. If so, the "Monkey Lower", "Monkey_Shaft", and "MonkeyUpper" room names were likely in reference to the structure of the lair, with "Monkey_Shaft" serving to connect the lower and upper portions of the lair.
