The phrase in question refers to the character Android 21 from the Dragon Ball franchise in conjunction with content of an explicitly sexual or pornographic nature, often found and shared online. This falls under a broad internet phenomenon where fictional characters are depicted in sexually explicit ways, frequently violating copyright and trademark protections. The expression combines a proper noun identifying the character with a descriptor indicating the nature of the associated material.
The proliferation of such content raises complex issues related to intellectual property rights, artistic expression, and the potential exploitation of fictional characters. Copyright holders possess legal claims against unauthorized reproduction and distribution of their characters. However, the sheer volume of user-generated content on the internet makes enforcement challenging. The historical context reveals a long-standing tension between copyright law and fan-created content, with “rule 34” representing an extreme manifestation of this conflict.
