Avatar 2.0, commonly misnamed Robloxian 4.0, was designed to replace the ROBLOX character as a whole, instead of simply being a package.

Luckily, Avatar 2.0 has been scrapped by ROBLOX, but it has been replaced by R15, an equally terrible creation.

Currently, BC'ers can test R15, and can switch their game to utilise R15 characters.
