Liter
About
Liter is the leader of Mighty Tools, a "squad" specialized in architecture and construction jobs throughout the Ark. Despite her diminutive size, Liter tends to talk like an elderly lady, owing to the long life she's lived as a Nikke. She's almost always seen with her robotic dog companion Bolt (sometimes spelled as Volt), and has a pet peeve for things being unclean and disorderly.
She is the leader of Mighty Tools. Contrary to her appearance, she has already lived a long life. At present, no other Nikke can surpass her when it comes to construction.
Despite her size and demeanor resembling that of a child, Liter speaks like an old woman being matured than her looks, growing tired and highly critical of the younger ones.
Before the events of the game, Liter was a Nikke under the command of Josh Hummett. She herself cared little about her life and future, but that changed when her commander died while trying to save a Nikke from Raptures. Seeing how his reputation since was either forgotten at best and smeared at worst, Liter wants to build a legacy for herself before she passes.
