Alex Kidd

Alex Kidd is a video game series starring Alex Kidd, a character often thought of as Sega's earliest mascot. Most games in the series differ heavily from one another, with the exception of Miracle World and its sequel Enchanted Castle. Quite often, the only thing linking the games together was the fact that they were side scrolling and platform based.

A year after Alex Kidd in Shinobi World was released, Sonic the Hedgehog was unleashed upon the world. The title character, Sonic the Hedgehog, wound up being much more popular that Alex Kidd, and thus, no further Alex Kidd titles were developed as Sega decided to focus on Sonic games.
