Why remove it?
Due to licensing agreements with Paramount.
Netflix doesn't own most of the content it streams, it licenses it from studios and production companies for a set period.
Paramount are the one who decided how long it aired on Netflix.
So I guess everybody who still wants to watch it digitally has to go to Paramount +.
Oooh! Maybe they'll do exactly that! Dr. Robotnik returns, everyone's shocked, but it's later revealed top be Neo Metal Sonic.
I know I said they should give Dr. Robotnik a rest, or I’d be disappointed if they used an alternate version of him... but I would find Neo Metal Sonic disguised as him acceptable.
Yeah but it won't be a twist for Sonic fans since most of us has already read the IDW Comics.
