SteamトレーディングカードのBobには"Just realized he's not coming home.(彼が帰還してないのに今気が付いた。)"という説明が記載されている。
Bob seems to be the least famous of the original three with fewer search hits than Bill Kerman, who has far less than Jebediah Kerman. It's unclear what, if any, consensus fans have of Bob Kerman's character, role, or attitude. In an unofficial video by fan 'EventHorizon5' Bob is depicted as somewhat anxious and unassertive in "Bobbing Around in Space". In the equally unofficial fanwork Kerbal Comics, Bob is depicted as young, eager, scared, and not too bright.
