I know an example. A tech lead who would demand every single task to be done in certain ways and go through a certain processes. Invading other team's PRs and slack channels in order to pick fights because they weren't using his microservice or his libraries. Claiming "if you're not working like us, then you're wrong". Asking people to make PRs but then not approving. Before being demoted, his team had ZERO new features delivered for about a quarter. To me that's an example of slowing down teams.

But if you mean you want someone "brilliant, but an asshole", then I agree with you. I find that the common examples are more about incompetent managers who can't make the best of an IC who can work well in isolation.
