SUPERBOY 197 (September 1973)--1st story, "Timber Wolf: Dead Hero, Live Executioner" by Bates and Cockrum; cover art by Cockrum and Cardy:
With this issue the Legion become the main feature of the book. However, the story does begin with Clark Kent and Lana Lang in Smallville, sitting under the apple tree. Lana wants to know why her best friend never tries to get fresh with her.
This is an uncomfortable situation for Clark--and to add to his worries, he's just got a signal from the Legion to come to the 30th century right away. He uses heat-vision to knock out Lana with falling apples and heads through the time barrier.
But he's only been brought there by the L.S.H. to see Timber Wolf.
In an unrecorded case, S.B. and T.W. were on a mission together in space, when a planetoid exploded presumably killing Brin. However, the reports of his death were greatly exaggerated.
It later turns out, when Timber Wolf attempts to assassinate the President of Earth, that he's been brainwashed.
The culprit is Tyr, who reveals himself when he attacks Saturn Girl in Legion H.Q.--his real objective was always to blow up the Legion's citadel and everyone inside. Brin overcomes his brainwashing and saves Imra from Tyr--but the villain's gun hand escapes.
Note: The idea that any alert from the future needs to be answered immediately makes no sense. But it's a quirk of these time travel stories the reader simply has to accept.
Art note: Dave Cockrum gives Brin Londo his new look with this story.
