Item-1 is required to reach a ladder in the first Wily Castle stage, and can be used to bypass some walls in Boobeam Trap's room, saving Crash Bomber energy. During the fight with Air Man, if Mega Man stands on an Item-1 platform, Air Man will not blow his tornadoes.
Item-1 is also available in the Wily Tower mode from Mega Man: The Wily Wars.
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-3s, after Mega Man had been restored to his regular state of mind, but only Item-2 is used by him.
After Heat Man's defeat, Dr. Light appears and equips Item-1 on Mega Man while explaining how it works and what will be his next object. Mega Man later used Item-1 in Wily's fortress to reach a ladder, to temporarily avoid the Metalls from Guts Tank, and in Boobeam Trap's room.
While not seen in the manga, Item-2's description notes that Item-1 and Item-3 also exist, but Item-2 was best suited for the urgent nature of Mega Man's situation.
Item-1, alongside Item-2 and 3, appeared in one of the shorts from Ryūzō Sotoma, where Roll considers them the most useful supports for her tasks, using Item-1 to change a lamp.
