DELTA

DELTA is a robot researcher in Pikmin Forever who crash-lands on PNF-404, and who meets with Captain Olimar, becoming the second playable leader in the story. She is the latest test of the KHA explorer-technology relations program: a robotic space explorer that can function alongside other explorers with adaptive reasoning and feeling. She begins her research mission to PNF-404 with Edward as a standard helper robot with simple synapses and understanding; their KHA Lander crash-lands and she falls into the the Scalding Thicket. However, as she finds Olimar and ventures on in the story, her synapses develop into a complex mind that can understand even the complexity of the Pikmin and Onions. As DELTA progresses, she figures out much about herself and the mission's design: for example, she notes that she has a spacesuit (which she ordinarily would not need) to make her appear more approachable than a regular robot skeleton. She also figures out that the KHA eventually intends to replace its space program staff with robots. Toward the end of the story she becomes self-aware, and enjoys the friendship of Olimar and Loucap too much to let them be replaced by robots.

In the game, DELTA is unlocked as a leader by defeating the Emperor Bulblax in the Emperor's Crown. She can run a bit faster than other leaders; other leaders keep up with her when following her, making her best for trekking long distances. Her whistle also expands faster than other leaders' whistles, although hers lasts a bit less time. These differences do not exist in Challenge Mode, but they can be allowed in Sandbox.
