The series in general
- Market-Based Title
- The Mark III version was titled Super Wonder Boy, presumably to distinguish it from the earlier SG-1000 version released exclusively in Japan, since the Mark III was backwards-compatible with all SG-1000 games (also doubles as an Updated Re-release, as two extra areas were added and the dolls were given purpose besides points).
- For some reason, the Game Gear version (based on the above release) was titled Revenge of Drancon in North America (it was simply called Wonder Boy everywhere else).
- More Popular Spin-off: The Monster World sub-series. There's a reason why the PS2 compilation was titled the Monster World: Complete Collection and not the Wonder Boy Collection.
- Demonic Spiders: The frogs (which are extremely hard to hit before they jump into you) and the literal spiders that appear in droves in later stages.
- Goddamned Bats: Bees, rocks, bats, octopuses, swordfishes, etc.
Wonder Boy in Monster Land
- Porting Disaster: The Amiga version had stumpy graphics and tinny sound, did not label shop doors, and had a small play area to fit the status border. (The Master System version instead compressed the HUD into a small bar and put the rest of the info in a pause menu, resulting in a much more playable screen size.)
Wonder Boy III: Monster Lair
- Porting Disaster: The Mega Drive version had its graphics horribly mutilated, even worse music than the arcade version, and is missing the shmup stages from levels 5, 6, 9, 12, and 13 due to lack of ROM space.
Wonder Boy III: The Dragon's Trap
- Ear Worm: The dragon bosses' battle song. Enjoy: http://www.youtube.com/watch?v=eHeOUvA5CLo
- This installment is well known among the fan community as having some of the most memorable music in the series.
Wonder Boy Returns
- Genre Throwback: The general fan consensus was that returning to the original gameplay was unnecessary, as it was not anything that Monster Lair or the Adventure Island series had already done better. It doesn't help that the game looks more like a dated budget mobile game and was released in the shadow of Monster Boy And The Cursed Kingdom and the Wonder Boy: The Dragon's Trap remake.
