Part 2: "Mento Meets the Atom Masters"

This story is continued from the first story of Doom Patrol #105.

Synopsis:
Suspecting their involvement with his young ward, Galtry finances the experiments of Mr. 103 in return for his promised destruction of the Doom Patrol. The Patrol is on the verge of being defeated by the atomic villain when Mento, searching for his missing wife, intervenes to turn the battle in the heroes' favor. Having ingested the meteoric element he stole, Mr. 103 is now invulnerable to the Chief's ray-weapon, but a side-effect traps him in a highly radioactive form, and he is almost destroyed before the Chief discovers a way to save his life.

Reneging on his promise to surrender if he were saved, Mr. 103 escapes, but not before the Doom Patrol learns of his involvement with Galtry. This information leads Steve Dayton to instigate an investigation of Galtry's finances.
