Robonyan F, being an upgraded version of Robonyan, has a very similar machine-like personality like him. As a difference, it should be said he is a bit boastful about his upgrades to the original Robonyan; however, he is level-headed enough to recognize the original's pros.
Robonyan F's abilities are very similar to Robonyan; however, him being an upgrade, his are further enhanced: for example, he can turn into a chocobar factory, and shoot powerful missiles capable of wiping out an island.

Robonyan F is an upgraded version of Robonyan from a further future. Although they end up in a competition about which model has the best schematics with Model F victorious, he commends the original Robonyan about his pros. Upon witnessing Robonyan F's sacrifice to save Earth from a meteor, Robonyan is inspired by him to the point to upgrade himself to be equal to him, much to surprise of Nathan Adams and Whisper.
