Somari the Adventurer (commonly known as simply Somari is a side-scrolling platform video game for the Family Computer. An unlicensed remake of Sega's 1991 Sega Genesis/Mega Drive game Sonic the Hedgehog, the game was sold primarily around Asia, Russia, Eastern Europe, and other regions where bootleg NES and Famicom cartridges were distributed. Like the original, players venture to defeat the mad scientist Dr. Robotnik, who plots to turn the animal population of the fictional South Island into evil robots. Unlike the original, the game features Nintendo's mascot Mario as the main character rather than Sonic. The title is a portmanteau of "Sonic" and "Mario".
