Blok

A silicon-based lifeform from the planet Dryad, Blok possesses a massive stone body granting extraordinary strength and near-invulnerability. After initially clashing with the Legion of Super-Heroes as a member of the League of Super-Assassins, he ultimately joined the Legion's ranks as a full-fledged member.

Few Bronze Age debuts carry the creative pedigree of Blok's arrival in The Legion of Super-Heroes #272 (1981), brought to life by the legendary Steve Ditko alongside Gerry Conway and Frank Chiaramonte. This DC character stepped onto the page in an era when the Legion's sprawling 30th-century universe was firing on all cylinders, and Blok has kept remarkable company ever since — sharing adventures across decades with luminaries like Saturn Girl, Lightning Lad, and the brilliant Querl Dox. With 53 catalog appearances spread across The Legion of Super-Heroes, Tales of the Legion of Super-Heroes, and beyond — stretching an impressive 45 years from 1981 all the way to 2026 — Blok is a testament to quiet, enduring staying power in one of DC's most beloved cosmic corners. Three key-issue appearances underscore the collector appeal here: this is a character worth tracking down for any fan who loves the Legion's rich, sprawling mythology.
