Chosen One

The Chosen One is the person tasked with protecting the world from monsters, demons, and assorted other baddies, including the Ultimate Evil, in Daniel Kravitz, Chosen One, a segment of It's All Been Done Radio Hour. The Chosen One has above-average strength and speed, though his or her fighting skills must be honed, as any combatant would train. The Chosen One does not possess psychic abilities. They are almost never old ("Three's Company").
Monsters can sense the Chosen One energy, making those who possess and use it easily located ("Childish Thing"). Most don't act upon this because they fear the Ultimate Evil, who has staked at the Chosen One as its target and requires permission to go after the special human ("...And Sprinkles On Top"). Chosen Ones are immune to witch magic, as well as the kind the U.L.P. used ("Wanda's Wand; Pit of Despair"). But they are vulnerable to other types of spells ("Cave of Wonders"). 
Some Chosen Ones have displayed magical powers, as well. Once thought to be a myth, these abilities resurfaced in Daniel Kravitz. They can do a Disappearing Retreat, similar to a smoke bomb with teleportation, allowing them to escape a fight ("State of Disbelief"). They also have Stun Wave, which temporarily knocks an enemy force unconscious, sparing any allies by their side, and can track their way to an enemy ("Into the Darkness"). Thirdly, they have Quick Heal ("Cave of Wonders"), which can also be used on others ("With Great Power..."), and speeds up their metabolism so much that they have difficulty getting drunk ("A Chosen One Walks Into a Bar"). 
Such powers were meant to be used sparingly, and would exhaust a Chosen One who used them too often ("Jant Braidley"). This leads the trainees to theorize Daniel might be able to further tap into the power of past Chosen Ones, but has not yet ("Daniel Kravitz of Antique Shop vs. Geralt of Rivia"). 
The Chosen One is overseen from afar by the U.L.P., who send a mentor to train and advise them. The set rules, or at least guidelines, frowning on any Chosen One being involved in a romantic relationship. It is unknown how the Chosen Ones are picked, but the U.L.P. does not make that decision; the organization merely has means to find the individual when a new one is tapped ("The Hub").
Throughout history, the U.L.P. has often been corrupted by bad leadership ("Pit of Despair"). This, combined with the dangerous mission of the Chosen One, has led to very brief tenures for most who have held the role, with few lasting more than a year.
It isn't clear how a person becomes the Chosen One, with some debating which ancient belief systems, including the Aztecs and the Egyptians, might be true, or partially so ("Get Out").
