Y'know, I miss this show (Medabots, or in Japan, rather hilariously "Medarots").
It's kind of unfortunate that they chose to dub Metabee here with what is generally considered a "black" voice, because it brings up questions of whether the dubbers were stereotyping.
But then, a very large number of the children watching the show would never have heard of the stereotype (I know that I'd never heard of it until sometime in the last year or so while perusing TVTropes), so it feels more like political correctness obsession ruining things than anything for me.
In case you want the negativity inherent in the first part of this post flushed out, here's one of the series' more awesome moments.
The awesome part isn't actually that three robots suddenly tapped into their secret powers to fire off giant blasts of energy which nothing could survive. It's that (while you don't see it here) their target ultimately shrugged it off.
