Well, finally got my volume 18 in yesterday and was able to fully read it today. Seems alright, despite some quirks. (that I was able to compare with the original, since I actually have 18

)
Names of people and things:
Kika and Kami-sama remain. More on the first one later.
Saiyan is the standard. There's no Saiyanjin here lol.
Rei Enma. (Rei being portuguese for King)
We have Kaioh and Kaioh-sama, which is great. There's also Kaioh-Ken and Genki Dama.
Last, but not least......Saibaiman.
There are a few...awkward lines here, though. When Gohan is up on the cliff peeing, Piccolo says "Faz chichi." ("He's peeing").....CHICHI. Why do we have Kika?... Since it is pronounced shee-shee in portuguese, I'd even be okay with "Tchi-Tchi" or something....oh, well.
Nappa reveals that Piccolo is a Namekian, thus, an alien. In this version, Kami says something to the effect of "I didn't think I was an alien...I always wondered about the antenna, though...". Seemed hilariously strange lol. Sure enough, in the original, instead of the antenna comment, it's about him being "a little different" from everyone else.
Here, during Yamcha's fight, Piccolo tells Gohan that everyone can feel out their energy but himself. Weird typo, since he obviously meant Gohan, who wasn't being able to do so.
When Kuririn (here, Krillin...) attacks after Yamcha's death, Tenshinhan tells Chaozu to get away. Here, he says "Chaoz, stand back! I might hurt you!"....which doesn't make sense.
And with Nappa's powering up ends the first decent quality Dragon Ball manga release in Portugal.
