Luno Mapelhorn is Solvice's brother and the secondary antagonist, of T.T.F.N. 2.

In the beginning of T.T.F.N. 2, Luno somehow releases Game Overs into real life and forces Solvice to go through many trials in order to rid the world of them.

Luno is very mysterious.


  • Luno's name comes from the adjective for "moon", (lunar), because Solvice's name sounds much like the adjective for the Sun (solar).
