Spacesuit

Olimar's spacesuit is white with red gloves. It includes a clear helmet with a red antenna. There is also a small red pack on the back which contains a life-support system. In Pikmin 1, Olimar's suit can only function for 30 days before the life-support batteries fail. A popular theory as to why the Pikmin follow Olimar is that the antenna on his helmet resembles a Pikmin stalk, therefore they view him as a Pikmin king.

Olimar's suit will spark when he takes damage from an enemy or hazard, and the health meter in the bottom-left corner of the screen will decrease. After Olimar is reduced to less than half his health, the meter will start to flash and a beeping noise will be heard. Any damage taken can be regenerated by standing in the light of the Dolphin and pressing A. This will not work with the Ship in Pikmin 2, so any damage is regenerated at the start of each day, as in Pikmin 1.

When Olimar whistles to Pikmin, the antenna will emit rings of light which spread out at the point where the pointer is. Another theory is that Olimar's antenna sends out radio signals when he whistles, and the Pikmin are responding to these signals.

Pikmin 2:Louie and the President

In Pikmin 2, Olimar is joined by Louie (and later on, the president), whose spacesuit is similar in appearance to Olimar's, except that the gloves, pack and antenna are blue. The spacesuits' life-support systems are powered by the Ship, eliminating the need for a day limit.

The President's spacesuit is different to Olimar and Louie's, in that it is mainly composed of the suit that he was wearing on Hocotate. This suggests that the suit is airtight. The suit also includes golden gloves and pack, with a blue light. The President's whistle is also different to the other two; it sounds more like a car horn.

All health lost

If Olimar loses all his health, the message Olimar is Down! will be displayed, the day will end, and all working or idle Pikmin not under an Onion or the Dolphin will be eaten as normal. Olimar's health will be replenished at the start of the next day.
