Blue Beetle #51

This 1965 Charlton entry introduces Mentor the Magnificent right on the cover, where a powerfully built figure bearing a bold "M" on his chest looms over a struggling Blue Beetle, who gasps "I'm weak… sick… he's beaten me!" while his opponent boasts of stealing the hero's very power source. Tony Tallarico's cover art captures the drama vividly — fireworks erupting in the night sky behind the two combatants as Blue Beetle is brought to his knees. A bottom banner promises the transformation of a timid weakling into a mighty, indestructible monster, making this a genuinely compelling issue to track down.
