Synopsis:
Zook witnesses a bank robbery in the town of Woodsville committed by a strange alien creature named Thantos. Thantos is working with a group of Earth criminals. Zook destroys their car, but Thantos flies them to safety. 3000 miles away the Martian Manhunter hears about the robbery. Since Vulture has been inactive recently, he decides to return to America to investigate.

During J'onn's first encounter with Thantos, the alien splits into three beings and escapes. Zook then tracks down the Earth criminals and learns that Thantos is from another dimension and needs several items in order to remain in this dimension.

J'onn then meets Thantos again as the alien is stealing the other needed objects. Thantos manages to steal everything he needs, then disappears into his home dimension. Zook fears that the alien can now return to Earth whenever he wants. However, J'onn had taken a pouch containing one of the necessary objects from Thantos before he disappeared. Thantos is therefore unable to leave his own dimension to threaten Earth again.
