Professor Ivo

Anthony Ives is a brilliant but obsessed scientist who achieved immortality through his own experimental work — a gift that became a curse, leaving him desperate to find death's release. He is counted among a rare group of thirteen immortals fated to walk the Earth indefinitely.

Few villains can claim they've been a thorn in the side of DC's mightiest heroes since the Silver Age, but Professor Ivo has done exactly that — debuting in The Brave and the Bold #30 in 1960, conjured into existence by the legendary team of Gardner Fox and Mike Sekowsky. Across an remarkable 65-year span, this scheming scientific mind has kept some of the most iconic company imaginable, sharing pages with Superman, Wonder Woman, Green Lantern, and The Flash — the very pillars of the DC universe — as well as turning up across titles like Justice League of America and Batman: The Brave and the Bold. That kind of endurance, from the optimistic rocket-age dawn of the Silver Age all the way to the present day, marks Ivo as one of DC's quietly indispensable antagonists, a cerebral menace whose ambitions have never gone out of style.
