The "MechaHitler" things is particularly obvious in my opinion, it aligns so closely to Musk's weird trying-to-be-funny thing that he does.

There's basically no way an LLM would come up with a name for itself that it consistently uses unless it's extensively referred to by that name in the training data (which is almost definitely not the case here for public data since I doubt anyone on Earth has ever referred to Grok as "MechaHitler" prior to now) or it's added in some kind of extra system prompt. The name seems very obviously intentional.

Most LLMs, even pretty small ones, easily come up with creative names like that, depending on the prompt/conversation route.

Grok was just repeating and expanding on things. Someone either said MechaHitler or mentioned Wolfenstein. If Grok searches Yandex and X, he's going to get quite a lot of crazy ideas. Someone tricked him with a fake article of a woman with a Jewish name saying bad things about flood victims.
