Similarity between Tetsuwan Atom and Rockman?

[Toshio Tenma]

As far few people knows, the Rockman series got a lot of inspiration in Tetsuwan Atom like the fact he is a robot who fights for peace between humans and robots (though, that theme was dropped in the Rockman X and Rockman Zero series since a virus make robots to destroy other robots and even kill people). Funny thing about Rockman is the name of the character (without the blue armor): Rock. As the fans of Tezuka works, may now of Rock Holmes who plays several villain and antihero roles in early Tezuka works that would even funny if somebody did a crossover fanfic which Rock Holmes start to cause trouble at the city which Rockman lives and the hero must capture him. Also, many may think the name "Zero Saber". By the way, the name Zero seems to have appeared in Astro Boy Original anime and manga. Although I suppose it was just the adapted american name since "Denkou" was the name used for 1980 version and the 2003 anime. In Tetsuwan Atom there are even a gangster character with the name "Wily" who appears briefly. If somebody knows more about similarities and perhaps even possible source of inspiration then share here.

Rockman also got some elements from Casshern, like the robot dog (Friender and Rush). It might have some more, but I haven't watched the original series from 1973

We must remember that Rush only came in Rockman 3 and Casshern is a cyborg rather than a full robot.

The creation of Rush was a way to remove the special itens from Rockman 1 and 2 which allowed Rockman to reach certain areas.

Plus Atom had a normal dog in the 1980 which even helped as a sidekick sometimes, but during the creation of 2003 series it was obsolete. Specially considering events which Dr. Tenma shut Atom down and goes into hidding. So it would be difficult to put a pet dog in the story... Who would take care of it?
