4010 is a Nightmare featured in Episode 3 of The Dreamscape Ruckus. It is one of the Scaredboards in the Matrix Halls, being the first one to appear in the Episode, as well as the first Nightmare to be shown in the Dreamscape.
4010 is the "leader" of the Scaredboards, and is mocked by Def3 and nua for being the slowest. 4010 is often left behind by its mates because waiting for them would "slow down the mission". In Episode 3, it is the last to start chasing Dalsie through the halls.
Appearance
Like the other main Scaredboards, 4010 is a cardboard cutout of G'joob, a Mythical Monster, atop of a utility cart. Its irises are yellow instead of G'joobs usual blue.
Personality
4010 has issues related to its stubborn nature, including refusing to do something simply because someone ruined its mood. It has a like-hate relationship with 5uu9, as it tends to tease them a lot for their slowness. A lot of its personality traits seem to resemble G'joob.
