Extroverted Feeling (Fe): Leto is blessed with charisma, and is very popular among the noble families of the empire – so much so that even the emperor himself is afraid of his influence. Even though he realizes the necessity of waging war against the Harkonnens, he hates actually doing it, because it requires the killing of people who just happen to be in the way. Leto is someone who cares very much about others: not only his family, but also lowly people he doesn’t know, and the lengths he goes to in order to help people out can win over even those who expected the worst of him. When he is assigned to govern Arrakis, he would rather work with the native Fremen than work against them.

Introverted Intuition (Ni): According to Leto, the first step to avoiding a trap is knowing where it is. Indeed, the duke is fully aware that Emperor Shaddam IV is setting him up for a calamity in ordering him to rule over Arrakis. Leto sees the potential of the Fremen as a fighting force that his family could use to their advantage. He also tries to think a step ahead of his enemies at all times. Even though Leto loves his concubine, Jessica, and treats her as his de facto wife, he will not marry her so as to remain available for a political marriage in the future.

Extroverted Sensing (Se): Even though Leto is a compassionate and caring person, his ruthless side reveals itself whenever anyone threatens his family. He is especially decisive in dealing with his family’s arch-enemy, Baron Vladimir Harkonnen. Leto can take quick action to save people when he needs to, and he will often know the best thing to do instantly. At the crucial time when he has a chance to kill Baron Harkonnen, he fails in his attempt due to recklessness.

Introverted Thinking (Ti): Although Leto is an insightful man who can anticipate dangers, rational analysis is his weak point. Even though his family’s fate hangs by a thread as soon as they move to Arrakis, Leto does not believe that his own death is inevitable. Rather, he casts around for something, anything, that can help him survive. Through it all, though, Leto is aware of his own shortcomings in the logic department, and seeks to mitigate his weaknesses through his advisers (Thufir Hawat, Gurney Halleck).
