Another important thing is that both Kikaider and Metalder got inspiration from Tetsuwan Atom, but with the exception that they change their human like body to a battle robot body when necessary.
They're artificial humans who both have feelings, but they mostly deal with an evil organization bent into destroying the world rather than be looked down by humans like Atom had to deal.
So, these noobs don't know anything and have no room to talk about "rip-off".
