The only way i can see this not getting a lawsuit is if they explicitly state its a parody but uhh from what im seeing its def not a parody and even then im pretty sure theres a chance dw can still sue them
Most fanart such as charms and zines etc go under the radar since 1) free publicity 2) for the most part its under a good light and no maajor profit is being made
However, this voltron reboot here is going to get law suited so fast if they even get anywhere past talking
