From threeA Wiki
Zeroday Popbot, also known as Day One Popbot, is a character in the Popbot universe. The name "Day One" comes from the day Popbot appeared when he was first created. Zeroday Popbot was available only through the 3AA Exclusive Yesterdays Future Pack which also included the Tomorrow King General Showa. Unlike other Popbot toys released at the same time, no satchel was included with Zeroday Popbot.
