The three brothers are called ASL as a trio. Ace is grumpy, stoic, teasing, cold and a tsundere, takes time to open up. Sabo is cheeky, sly, polite, curious and calm, while Luffy is energetic, perky, happy, definitely very emotional and a crybaby at times. All three are loyal, more innocent like as they are children, and mischevious, liking to have adventures and such.
