Basic Trope: The ability to give someone else an ability.
Straight: In Heroes of Troperia, The Sage Al-Mu'alim can give someone super power, which he did to Bob, making him a standard-issue Flying Brick.
Exaggerated: Every single heroes ever in Heroes of Troperia was empowered by the immortal Al-Mu'alim. Which gives way to a lot of Fridge Logic.
Downplayed: Al-Mu'alim teach Bob the theory behind a Flying Brick superhero, which Bob then practice with great success.
Justified: Al-Mu'alim is a deity, a celestial, or someone of great power who is barred from acting (too) directly in the world, so he set us up some superheroes.
Inverted: Al-Mu'alim drains power from superheroes.
Bob bludgeons Al-Mu'alim and then absconds with the poor old man's powers.
Subverted: Bob really can awaken by himself, Al-Mu'alim is just taking advantage of Bob's ignorance.
Double Subverted: When Bob confronts Al-Mu'alim about this, the incensed sage takes Bob's power away. "You would rather listen to someone shady you just met, than me who gave you power for free?!"
Zig Zagged: Mu'alim gave Bob powers to carry out his quest, then Bob discovers he already had powers, only for Mu'alim to reveal that he gave Bob a hidden power to save him in the final battle... and it's Heart.Great, just great.
Averted: All heroes learn, awaken, or (in case of Anti-Hero) steal their power, on their own.
Enforced: Making the concept of super powers more humane: it's given by someone who, despite great power and moral superiority, is more or less an approachable person; he or she who expects the heroes to use the power responsibly.
Discussed: "If this were a fantasy anime, we would have run into an old man with cryptic prophecy and an offer of power. Unfortunately we're not some kind of exalted knights going after a mythical dragon, we're patrolling this highway from bandits."
