The reason this article is a stub is because there is nothing much to say about him. He is a grotesque who apparently has the electrified affix and is needed for an achievement. All this information can be condensed onto the Grotesque article. Anything else can be added in the note column (why there is one).
This is why I recommend redirecting all Unique monster articles to their base monster type page. The redirects are structured such that it will even redirect to the very table entry of the unique monster.
