Item-1

Item-1 (アイテム１号 Aitemu 1 Gou) is a levitating platform from Mega Man 2 that Dr. Light gives to Mega Man when Heat Man is defeated. It's possible to have three platforms on screen at once. This item is required to reach a ladder in the first Wily Castle stage. During the fight with Air Man, if Mega Man stands on an Item-1 platform, Air Man will not blow his tornadoes. Each platform consumes 2 units of energy.

Archie Comics
In the Archie Comics Mega Man series, Dr. Light supplied Mega Man, via Cut Man, with program data that allowed Mega Man to utilize Item-1s, alongside Item-2s and Item-3, after Mega Man had been restored to his regular state of mind.
