>>3885654eh, he doesn't have the most to him, so it's more so up to interpretation.
The MOTHER novelization by Saori Kumi (who deemed to call him Ken) made him a little shit.
Encyclopedia MOTHER (official guidebook out of many and also lore book, and if I recall correctly was published by APE Inc. themselves) made him an average nice kinda american boy, but made him a fan of George Lucas movies (considering they mention Indiana Jones and also Star Wars in his bio of sorts) and whatnot.
so basically, with Ninten, he's almost a full blank slate for you, the player. You decide what he's like to you.
