Ikthon

A creature of the deep born in Marvel's Silver Age, Ikthon surfaced in 1970's Sub-Mariner #31, brought to life by the legendary creative duo of Roy Thomas and Sal Buscema. This rare figure from the undersea corners of the Marvel Universe has crossed paths with some genuinely formidable company — Sub-Mariner himself, Lady Dorma, and the fearsome Tiger Shark among them — which speaks to the dramatic, high-stakes waters Ikthon inhabits. Appearing across titles like Tales to Astonish and The New Mutants Annual over nearly two decades, Ikthon is the kind of obscure Silver Age discovery that makes deep-diving Marvel collectors feel like they've found something truly special.
