What System Was Mario's First Appearance On?

Mario debuted in the arcade game Donkey Kong (July 1981), running on Nintendo's proprietary "Donkey Kong" arcade hardware (based on the Zilog Z80 CPU).

Key Details

• Character Name: He was called "Jumpman" in the original Japanese and US cabinet instructions. "Mario" was adopted later (named after Nintendo of America's landlord, Mario Segale).
• Role: Player character (carpenter, not yet plumber) rescuing "Lady" (later Pauline) from Donkey Kong.
• Home Console Port: The first home version was on the ColecoVision (1982), then Atari 2600, Intellivision, and others.

First "Mario" Title & NES Debut

• Mario Bros. (Arcade, 1983) – First game with "Mario" in the title; introduced Luigi, pipes, turtles, POW blocks. Still arcade hardware.
• Super Mario Bros. (NES/Famicom, 1985) – First *scrolling* platformer, established Mushroom Kingdom, Peach, Bowser, power-ups. This is the game that made Mario a global icon.

So: Arcade (Donkey Kong hardware) → First appearance. NES → First *home console* platformer with his name.
