Legend of Hero Tonma is a 1989 Irem Arcade platformer, known for its difficulty, brightly colored graphics and its rarity in the US. The game was converted to the TurboGrafx-16 in 1993 (based on the 1991 PC Engine version) making it one of the last games to be released for the system in the US. It was later added to the Wii's Virtual Console in 2007. The Arcade version was later ported for Mac and PC with Irem Arcade Hits.
The game is graphically similar to Wonder Boy, but is also structured similarly to Ghouls n' Ghosts. The player must pass through areas filled with enemies, trying to survive long enough to upgrade their fireballs to the point where it becomes far easier to cope.
