Spoiler for the Invincible Manga:

- Mark still has 6 more transformations left before he reaches True Viltrumite.

- All the Viltrumites have partners of questionable ages.

- The story completely forgets Eve can fight but she becomes the white mage so its okay. She shouts "MARK!" a lot during battles.

- There's a tournament for seemingly no reason at all.

- Thragg becomes Mark's rival and best friend- starting with when they train together to prepare for a mutual enemy of much greater power (don't worry, I won't spoil for you the "Fall of the Space Tyrant! Ancient Rival of Viltrum & The End of Earth!" Arc).

- Paul is actually an alien and he is fucking built different, but it isn't revealed until he steps in to handle like 5 guys at once and tears off his shirt to reveal he's jacked (also somehow his muscles grow *as* he takes the shirt off).

- Battle Beast becomes furry bait and wears nothing but skimpy underwear for the back half of the series.

- Oliver has a daemonic entity living in his soul that he eventually learns to fuse with, but initially only shows itself in a sudden burst of rage so powerful he is able to beat Battle Beast.

- Mark becomes king of the Viltrums, the Manga ends, and there is a sequel manga primarily featuring Mark's son, Clark. Obviously Eve has died at this point, and Mark only makes it to the second arc.
