G-Force is an interesting character. He and his sister Mach, were an attempt by me to create characters that had a bit of a flaw that they needed to overcome in order to prove themselves as not only heroes, but as people too. That flaw was a language barrier. Not really such a big deal, now that I think about it in hindsight, but that aspect of them was made-up years ago and I've never really thought of anything better, so it remains til this day, but of course it's something that they have indeed overcome and really isn't an issue anymore for them or any of their race.
