SMD

SMD is a mascot of not-well known Mascotia member Invader_ZIM_Fan (formerly WaCkO101). He shares the exact same personality as Invader_ZIM_Fan, and takes the appearance of a green cube with a screen that shows different faces according to SMD's mood (Although the screen has been shown to display more than faces, as shown when SMD shows a picture of GLaDOS from the Portal series). On the bottom of SMD, there are three supposed anti-gravity mechanisms, sometimes shown to emit bands of energy that resemble electricity. He has two yellow-greenish eyes with black pupils.

Trivia
SMD is based (in physical appearance and abilities) on IB, a mascot of the Mascotia member Shacho.

SMD, as stated by Invader_ZIM_Fan, stands for Status Machine Dude.

SMD is not an Ibian like IB, as evidenced by the 2 eyes (as opposed to 3) and the anti-gravity mechanisms. Rather, he is a different species, built in the likeness of the Ibians, dubbed Ibian A.I.s.

SMD has inspired many other Ibian A.I. mascots, though Invader_ZIM_Fan has stated he doesn't know what the deal is with SMD's popularity.

SMD used to have long, thin arms, but now they have been turned into retractible normal-lookng robot arms. Occassionally, SMD can switch his hand/claws with machine guns, and homage to Hasbro's popular The Transformers franchise.
