Sure! Figured it be cool if we'd be going to Namek, too.



So no scouters?
Maybe but I like the explanation other than 'there are a entire planet like him' -w-
@Hillan
It is mentioned by the creator himself when asked, and so yes it is cannon. The rest of his race is normal power levels, but does come with race based boosts such as surviving in space, tails etc.
"It was said by Akira Toriyama that Frieza was a "hybrid mutant" of his race (due to an accidental mutation a long time ago), and a hybrid refers to an entity that is born from two parents of separate species or variety."
@Hillan
Weeeeeeeeeeeeeeeel Arch is right. Look on the wiki and you will see Frieza AND his family are all mutants with abserdly high power levels. Though the transformation thing is normal for their race it simply hide their power not boosts it unlike golden, that is why Frieza has so many transformations because his power is boosted from being a mutant. So being apart of Frieza's race is 100% acceptable as they would likely be that weak.
<Snipped quote by Hillan>
Well Freeza's race can be that weak as apparently Freeza was just a prodigy AND a mutant or something like that.
As for Majin. Could say the same thing about Buu, or the Majin just isn't well trained or something. I mean the CaCs in Xenoverse have trouble with Raditz at the start :P. And thats RADITZ xD
You can fit Majin if you just fudge a bit of the lore a bit since technically NO ONE knows where Majin Buu came from with the current lore. And since Majin means Demon, I think Buu was just some Majin who went feral after being 'purified' with an experiment from the Demon Realm and was sent to the normal universe to avoid destruction there. Majin normally are the chefs/servants/ext of the demon realm since they don't have much of a lust for power unlike Dabora/Towa's race due to their Fat Buu playful/Food loving personalities.
Makes sense as to why there are so many Majin in Xenoverse and why Female Majin exist. (I know about the DBO thing, but XV2 is the closest thing to the west they have and Buu makes NO FEMALE Majin in that one.) Plus adds some much needed lore to both Majin AND the Demon Realm.
