Ariel

Ariel made her Marvel debut in the Bronze Age pages of Sub-Mariner #67 (1973), brought to life by the inventive Steve Gerber and artist Don Heck — a pairing that knew how to make an entrance. With two of her handful of appearances carrying key-issue status, she punches well above her weight in the collector world, and her catalog footprint stretches remarkably across nearly five decades, from 1973 all the way to 2021. She shares her adventures with some of Marvel's heaviest hitters — Namor, Spider-Man, Johnny Storm, Reed Richards — which tells you she moves in rarefied company, even if her appearances are select and all the more treasured for it.
