About this Issue

Dynamo #1 (August 1966) is the first solo title spun off from Tower Comics' flagship T.H.U.N.D.E.R. Agents series, marking Tower's direct acknowledgment that Leonard Brown's super-strong agent had become the breakout star of their line. The issue introduced Andor — a super-powered human raised by the underground Subterraneans — a morally complex villain-turned-rogue figure who returned in T.H.U.N.D.E.R. Agents #9, demonstrating that Tower was building serialized, consequence-bearing storytelling at a time when most Silver Age comics reset every issue. As a creative artifact, the book assembled three of the most distinctive visual voices of the era — Wally Wood, Steve Ditko, and Reed Crandall — in a single 68-page squarebound package, making it one of the densest showcases of Silver Age draftsmanship published outside of the major houses.

In "Menace from the Moon!", Len Brown’s mundane day takes a wild turn when he’s whisked from his office to Hong Kong and then deep beneath the Earth, caught in a global threat orchestrated by the Overlord’s plan for nuclear chaos. With the help of the mysterious Iron Maiden, Len must navigate treacherous landscapes and deadly traps, all while his chance to ask the Chief for a raise slips away. Written by Wally Wood and Tim Battersby, with dynamic art by Mike Sekowsky and inks by Frank Giacoia and Joe Giella, this 1966 adventure from Tower Comics features a cover by Wally Wood that captures the story’s high-stakes drama.

History

T.H.U.N.D.E.R. Agents was itself born from a concept scripter Len Brown had pitched to Wally Wood, shaped by the early-1960s spy-fi craze surrounding The Man from U.N.C.L.E. and the James Bond films; Wood developed it into Tower's signature superhero line beginning in November 1965. Tower Comics, part of Harry Shorten's Tower Publications paperback empire, positioned itself unusually in the marketplace by publishing 25-cent, 64-to-68-page squarebound comics at more than twice the standard cover price — a format that gave each issue the feel of a curated anthology. Within roughly nine months of T.H.U.N.D.E.R. Agents #1, Dynamo's popularity warranted his own title, launched in August 1966 with Wood providing the cover and interior art on the lead story; detailed production credits documented in Alter Ego #152 (May 2018) through Tim Battersby's work records clarify that several scripts credited solely to Wood were collaborative efforts with Battersby, revised and plotted by Wood.

Trivia · 8 facts

  • First solo title starring Dynamo (Leonard Brown), spinning out of T.H.U.N.D.E.R. Agents after fewer than ten issues of the parent series — published August 1966 by Tower Comics.
  • Contains the first appearance of Andor, a human orphan raised and mentally conditioned by the subterranean Overlord's scientist Lord Uru, who rebels and kills his creator — penciled by Steve Ditko, inked by Wally Wood.
  • Cover and lead story ('Menace from the Moon,' 14 pages) are both fully penciled and inked by Wally Wood, with lettering by Ben Oda.
  • The issue is a 68-page, full-color squarebound Giant — Tower's standard format, priced at 25 cents versus the 12-cent standard of the era — and contains five complete stories.

  • Includes the debut of the recurring backup feature 'Wonder Weed, Super Hero,' spotlighting Weed — an unpowered T.H.U.N.D.E.R. Squad agent widely regarded as Wood's self-deprecating alter ego — art by John Giunta.
