Recurring claims — circulating most intensely during Kim Jong-un's extended absence from public view in 2014 and again during a two-week disappearance in 2020 — assert that one or more body doubles routinely substitute for the North Korean leader in public appearances. Evidence cited includes perceived variations in facial features across years (particularly ear-shape analysis and apparent weight-gain/loss cycles), gait changes, and a general argument from the known authoritarian-leader tradition of using doubles for security. South Korean intelligence (NIS) has not confirmed the claim; NK News, Reuters, AP, and BBC cover the gaps in what can be verified. The theory is treated here as plausible-but-unverifiable speculation.
