I watched Metalocalypse: Army of the Doomstar and Toki is a canonical age regressor who carrys a “Deadybear” around with him and the whole band accepts it and supports it and it’s not even a humorous focal point or anything. Pickles just says “Sorry, you know, Toki's a little sensitive these days. We think he's regressing from, you know, the whole thing.” When Toki has on outburst from being told not to something and other than him always having his comfort bear that’s the only way it’s mentioned, he is still the Toki we love.
It’s so nice to see regression presented in a legitimate way, Toki and the whole band went through hell, we see Nathan struggling with his own ptsd also. The fact that the whole band -including murderface who usually hits below the belt with his insults- just goes with it.
