Princess Bubblegum listing Earth's population before and after the Mushroom War.

This is a timeline of canon events in the Adventure Time series. To take track of the events in a good way, we need a year 0, in this case, that is the Mushroom War, most specifically, the explosion of the Mushroom Bomb, so the series events happened around 1000 years After Mushroom War (A.M.W.). ~100+ means that is more likely that happened more than 100 years after, in the same way, ~100- means that is more likely that happened less than 100 years after.

Distant past

  • According to the Lich, before the universe existed there was nothing, and before there was nothing, "there were monsters". The Lich and Orgalorg, existed as far as back then.
  • On Earth during the Cretaceous period, an Elemental, Urgence Evergreen, attempt to stop a green Catalyst Comet (the Lich) from hitting Earth, but the other Elementals, Chatsberry, Balthus, and Slimy D were opposed. The Ice Crown is created in an attempt to stop the comet from hitting earth, and as a result of Gunther's usage, causes its victims to become like his master Evergreen; or rather, how he saw Evergreen as: someone who is constantly firing ice magic and ordering people around.
  • Millennia ago, Orgalorg the warlord was banished by Grob Gob Glob Grod to Earth for attempting to intercept a yellow Catalyst Comet to gain its power. He is transformed into a penguin due to the planet's gravity.
  • At an unknown time, a blue Catalyst Comet hits Earth. It is later reborn as a butterfly and a pink lump with a gold outline (a "thing").

Upon wearing the crown he had said things that drove his fiance, Betty Grof run away from him, to later being brought to the present by a time machine that Simon built to say sorry to her.
  • ~1-0 years B.M.W: The Elementals of that time saw a future vision of the Mushroom War and Patience St. Pim freezes herself to survive.
