The '87 Update is the first post-Crisis entry. His entry in the original Who's Who covered Earths One & Two. The entry with the mechanical hand is in the '88 Update and was more about fleshing out his background since when the '87 Update was published he'd only been around for a little over a year. The could've probably just stuck him in the appendix but they might've already had the artwork from the Who's Who in Superman series that never happened.
