Which cartoon character is this? Name, source, all said, to be detailed!

Said by: C3 Rubik's Cube girl becomes a curse prop in human form, and the posture of human form is a little girl with blue hair. I like pancakes and hate clouds. Because I haven't been in contact with human society for a long time, I often stand out because of my lack of common sense, but everything with common sense is taught to me by Professor Chun Liang. "Curse you!" "shameless!" This is a kind of language addiction.

The body is a one-meter-long black cube with numerous iron plate combinations and 32 deformable organ shapes.
