In Mega Man 7, if certain conditions are met, Mega Man can battle Proto Man and, if he wins, he can actually obtain the shield. The shield is capable of blocking some projectiles (but only if Mega Man is still and is not shooting at the time).
In Super Adventure Rockman, Proto Man will drop his shield to save Mega Man from Sniper Joes in episode 2. Mega Man can use his shield if the player finds it by following the flashing arrows that appear in the sides of the screen, first finding an Information Card, and then the shield. When equipped, it reduces the damage Mega Man takes.
In Mega Man Powered Up, Proto Man can use the Proto Shield to deflect frontal attacks.
Appearances in other media
The Proto Shield appears in most media featuring Proto Man, like the Rockman manga series, the Mega Man Megamix manga series, and Rockman 10 -Extra F-, but is not present in the Mega Man animated series and in Mega Man: Upon a Star.
In the Rockman 7 manga, Proto Man challenges Mega Man for a fight before he goes to the Wily Castle. Mega Man wins the battle, and he gives the Proto Shield to Mega Man. Mega Man kept using the Proto Shield until it was broken during his second battle against Bass.
