Have you ever watched the moon rise over the Wasteland? I wish I could have given you something as wonderful as that.

Uncle Leo is a friendly, wandering Vault 87 super mutant that the Lone Wanderer may meet in The Super Mutant Philosopher random encounter in 2277.


Uncle Leo is a super mutant pacifist, who is embracing a spirit of giving and grace. He recalls his adventures to anyone who will listen. Uncle Leo gladly gives gifts to those in need, and reveals many facts about the genesis of super mutants (that they are not "born" but "created," for example).

Uncle Leo was exiled from his super mutant brethren because he was exhibiting peace-like attributes. They could not tolerate his message of peace and so they cast him out. Uncle Leo has roamed the Capital Wasteland ever since. If asked about his name, Uncle Leo will reply he has "always called himself that. Maybe it being his name before he became a mutant, or read it in a book a long time ago."

Effects of player's actions编辑

When the Lone Wanderer first speaks to Uncle Leo, he will express surprise that they have not shot at him yet. When a dialogue option appears to tell him to give up his goods (essentially "robbing" him), he gladly imparts a suit of dirty pre-War businesswear to the Wanderer as a gift, wishing he could give more.

Asking him what he meant when he said "before I became this" makes him reveal that super mutants are not born but are made by other super mutants in "a cold, dark, metal place." He mentions that they use the captives that they abducted to make more of themselves, but he either does not know or cannot explain how this is done.

Uncle Leo can be encountered a second and third time. He will tell the Lone Wanderer that after their first encounter with him he fell into a dark cave while climbing a hill and hurt his leg. The cave turned out to be an old basement in which there were stacks of purified water. He tells them that after he got out of the basement he has been hunted by a group of "bleeders" (as super mutants refer to humans) and that he was forced to abandon the water he was carrying. As with the first encounter, he will offer the Lone Wanderer another suit of dirty pre-War businesswear. At the third meeting, the Wanderer can express their concern for Uncle Leo, believing the Wasteland to be too dangerous for him; given his previous run-in with humans. He will explain that if he allowed his own worries to get the better of him, he would never take another step.

  • Uncle Leo is unarmed and wears only a pair of shorts.

He will also assist the Lone Wanderer in combat if he is nearby.
  • Uncle Leo is one of the two friendly super mutants in the game, the other being Fawkes.
  • Uncle Leo cannot be pickpocketed.
  • Uncle Leo remains in the game files of Fallout: New Vegas, however his skin color is the same as a Mariposa super mutant instead of yellow green.
  • If the Lone Wanderer happens to have Fawkes as a companion while meeting Uncle Leo a second time, he will express his shock at seeing another super mutant like him.

Notable quotes编辑

  • "I tried to get them to understand that there was more to life than fighting and killing, but they wouldn't listen."
  • "Have you ever watched the moon rise over the Wasteland? I wish I could have given you something as wonderful as that."
  • "You may be right. Most people I meet seem to feel the same way. I used to carry around much anger about my past, and fear about what would happen to me next. But it became so heavy I was not able to take even a single step. So I had to put it all down. It may be that I'm just not as strong as most people. I will have to think on these things."


Uncle Leo appears in Fallout 3.

Behind the scenes编辑

  • Uncle Leo's dialogue when the Lone Wanderer tries to rob him, where he tells them the clothes are a gift and he wishes he could give the Wanderer the "wonderful moon," comes from the following Zen Buddhist koan:
Ryokan, a Zen master, lived the simplest kind of life in a little hut at the foot of a mountain. One evening a thief visited the hut only to discover there was nothing to steal.

Ryokan returned and caught him. “You have come a long way to visit me,” he told the prowler, “and you should not return empty-handed. Please take my clothes as a gift.”
The thief was bewildered. He took the clothes and slunk away.

Ryokan sat naked, watching the moon. “Poor fellow,” he mused, “I wish I could have given him this beautiful moon.”
