I think it was the 80s vibe - back when humor was kind of lighthearted and not so racy (at least in kids programming). Also, robots shooting robots was not considered "violent" back in those days. Have you seen RID? Apparently, clubbing Decepticons with shock sticks is better than shooting them. I did not know that. In Kingdom Hearts, they gave Goofy a shield, rather than a sword. Because everyone knows that bludgeoning someone to death with a shield is far less violent than cleanly running them through. Eventually, TFs will just discuss their problems and resolve fights via verbal debate. Kind of like RB?
