Now the story of Ti-tan (whose name is a play-on the Japanese borrow word for titanium and the fact that the character has a very loud and destructive cry) was first featured in the pages of the magazine, "Mighty Atom Club".
The version in the magazine is a little different from the anime version. The synopsis as it appears in the "Mighty Atom Complete Book" is as follows:
Dr. Ochanomizu presents Atom with a new robot baby brother, Ti-tan. When Ti-tan is kidnapped, Atom flies to his rescue, but runs out of energy before he can get to him. However it is Ti-tan, himself who engineers his own escape by use of his super-loud wail.
The following image below is a "Mighty Atom Club" magazine cover which features Ti-tan.
