In "Adventure in Panama," Uncle Sam, Buddy, and Senator Corey are taken hostage aboard a plane bound for the Panama Canal, where a criminal gang seeks the documents in the Senator's briefcase. With the gang planning to destroy the Gatum Lake Spillway using a freighter full of explosives, Uncle Sam devises a daring plan to escape and turn the tide.

In "null," the Unknown confronts a Nazi commander whose reckless use of cocaine grants him superhuman strength—yet even that edge proves no match for the hero’s raw, unyielding power. Set against the tense backdrop of wartime espionage, this six-page tale pits brute force against instinct, with the Unknown’s quiet resolve standing firm.

In "The Spider of Doom," Jo's acquaintance, the mad scientist Professor Twitch, is murdered by his assistant Vang, who then unleashes a deadly army of giant killer spiders using the Professor's formula. With the city in peril, Merlin must impersonate Emperor Hirohito to outwit Vang and bring him to justice.
