No they aren't. I believe those are from one of the Brave toys - not sure which one. Not 100% sure on that, but I know they aren't Raiden parts.
They could be fakes. A KO taiwan version was released as well. Check for the copyright stamp. It should say "TAKARA" on it.
If they're real, that's not bad. Though, they appear to be missing all the parts, which kind of sucks, since their best mode is the combined robot mode.
The Brave/Yusha series(es) features many gems (and lots of recylcled TF molds, and a few not-so-hot designs) It's really one of my favorite Takara products. I often describe it as being like "Transformers without the Hasbro influence" Many of the lines are like the Japanese-only Transformers series (Victory being the prime example), only MORE Japanese-super-robot'y. But still *just* Tf'ish enough to not go off into Gundam/Sentai ga-ga land Shows are hard to find (Though I've tracked down most of 'em), but the toys are readily available, and BBTS even put up a whole slew of up-coming Korean-Sonoking(I think?) liscenced re-issues. Decently priced too! PM me if you want to know anything else D/L
