One half of the beloved Ice Climbers, along with her partner, Popo. Yet, when we are first introduced to the Ice Climbers, we find them aligned with this mysterious group headed by Dark Samus.  But..., Why? Older and wiser than she looks, Nana's demeanor is unsettlingly calm. She has a fascination for the weird and bizarre, and sees the world through somewhat-inverted lens.

Nana's tone can range from deadpan, to mildly sarcastic, to chilled and laid-back depending on her mood. In addition, since Popo almost never speaks, Nana is usually the voicepiece of the two.
