Basic Trope: The adventure begins on the protagonist's birthday.
- Straight: At the beginning of the story, Peter "Pro" Tagganist wakes up one morning to the announcement that it's his birthday.
- Exaggerated:
- Pro sees Humongous Mecha fighting, Godzilla rampaging, and a Colony Drop going his way in his birthday. And then a loud voice booming, "An Adventurer Is You!" and suddenly Pro is wielding a shiny sword.
- The entire story happens on the hero's birthday.
- The entire story begins with the hero's birth.
- Downplayed: The story begins on the birthday of the hero's sidekick.
- Justified:
- The prophecy the plot centers around specifically states that the day of the cataclysm will coincide with the day The Chosen One comes of age.
- One of Pro's birthday gifts, a family heirloom, turns out to be the crucial MacGuffin that kick-starts the plot.
- The villain targets the Five-Man Band of friends during Pro's celebrations.
- The heroes decide to explore, unleashing an evil.
- The heroes go to a place where the villains decide to strike.
- Inverted:
- The story ends on Pro's birthday.
- The story begins with the announcement of the villain's birthday. He decides to blow up Pro's hometown, causing him to seek revenge.
- Subverted:
- Pro wakes up at the story's beginning surrounded by party decorations... and remembers that it's his sister Ann's birthday.
- The villain attacks Pro during his birthday party, but, because of outside circumstances, Pro celebrated his birthday late. Pro's actual birthday was roughly a week before the villain's assault.
- Double Subverted:
- Then it turns out that they were born a year apart.
- The villain apologises for being late, mentioning that he wanted to attack on the hero's birthday but also wanted to interrupt their celebration. He states that he compromised by causing a few apparently unrelated strokes of misfortune on the actual date, since his evil oracle anticipated that it was an important day.
- Parodied: Emperor Evulz' zombie army arrives at the small town of Peaceville, and some townsfolk fight them back. Turns out every single one of them have the same birthday: that day.
- Zig Zagged: ???
- Averted: No birthdays are celebrated throughout the adventure.
- Enforced: "Parents are probably buying our games for their kids' birthday, let's have a resonance with that for extra impression."
- Lampshaded: "...And what do I get for my birthday? I get stuck having to save the world!"
- Invoked: Pro decides on his birthday to explore the Pyramids for treasure.
- Exploited: The sages searching for The Chosen One search in particular for someone who's celebrating their birthday on the day they find him.
- Defied: Pro decides not to do anything special on his birthday, reducing the chances of him being involved in an epic adventure.
- Discussed: "Look, it's Pro's birthday, right there at the beginning. That means he HAS to be the protagonist."
- Conversed: "Why do bad things always seem to happen on Pro's birthday?"
- Deconstructed: Pro's birthday begins as a joyous occasion until he walks out of a room and one of his presents blow up. He finds out it was a bomb from Emperor Evulz. None of Pro's friends except four nor family survived the explosion. He sets out his journey full of sadness and a desire for Revenge.
- Reconstructed: Pro then meets a Manic Pixie Dream Girl who reminds him that when he slays Emperor Evulz, his birthday will be celebrated as a major holiday. Thus, if he survives he'll have even better birthday parties afterwards. This ends up panning out.
Happy birthday! Head to Birthday Beginning to start the epic of your life!
