Species: robloxian
Robloxians are a plastic and robotic alien species found in the online game platform Roblox. They are characterized by blocky and rectangular (in general, less like realistic human body parts, and more like blocky-edged or noodly) limbs and torso, lack of [human] ears, a simplistic head shape, Lego-like hands (in the case of the subspecies, Robloxian 3.0), [often] unique/eccentric skin colors, flat or mostly-flat feet, and [usually] a lack of fingers or toes. Robloxians are more cartoony and simplistic than (realistic/anatomically correct) humans, but may get confused with the latter. They are made of plastic, but they are robots at the same time. They also often wear eccentric or futuristic hats, and may have characteristically human-like skin colors and/or hair. They can vary in shape due to the various bundles released on the Roblox website as well.
Though art exists featuring Robloxians with their canonical proportions (such as the example image above), Robloxians are often depicted in a more realistic and somewhat human-like style in fanart. In such cases, one can also tell that a character is a Robloxian by seeing if they are wearing clothes or head accessories available on the Roblox website, but art featuring Robloxians that are too human-like (i.e. cases where it is virtually impossible to tell that a character is a Robloxian due them being given a very realistic human shape and having many human features added) may not be relevant to eSix. Still, properly-tagged 1.0 and 3.0 Robloxians with visible Robloxian features and characteristics remain relevant.
The subspecies Robloxian 3.0 (the Man and Woman bundles on the Roblox website) is a Robloxian species, but not all Robloxians are Robloxian 3.0. The classic rectangular blocky style can be referred to as "1.0" to distinguish it from 3.0.
