Dr. Tenma in the 1963 anime.

[Tetsuwan Penguin]

So how many episodes did Dr. Tenma appear in in the 1963 anime?
1.The birth of Astro
2. The mystery of the metal men.
3. The Herald Brothers
4. Japanese People from space.

Any others?

BTW who is this guy from "Japanese People from space" A grown up Tobio?
Edit:
Apparently so. I later heard Atom call him "Tobio-san" The more I listen, the more words I pick up.

Indeed that's the alternate Tobio! I sort of remember a scene where this Tobio and Astro meet, and it was cute but also really sad. (Look how well Tobio would've grown up!)

I'm interested in seeing if there's more Tenma episodes, too. I ought to watch the rest of those four sometime.

See, I TOLD you guys Astro would grow up to be a hottie! Those big ears don't work for me, but he turned out WAY more handsome than his old man! I love this episode. Notice his hair is actually more like COBALT'S!

I wonder if grown up Tobio's character design is similar to the 'Astro Man' body Atom had in "Atom's been Stolen!"
