My reactions to these pictures and reveals :
Gotenks : Looks good, the face looks very faithful to me, though I see a few people disliking it. Not sure why. He looked oversized to me prior to these pictures but maybe it has grown on me or the angle is better because he looks spot on this time. I'm hoping it will also include a black and purple hair piece, and some translucent ghost.
Majin Buu : Looks amazing. I have the Banpresto Scultures one that fits well with Figuarts but I'll keep it so I can have both, I could use a posable one for the Dragonball Super display. At least the Scultures one came with a Biscuit Dabla stand/accessory so it's still pretty useful in a display.
New Goku : So happy I passed on the super expensive SDCC exclusive, I'll probably grab a couple of these to make a Namek version and a Saiyan Blue version.
Roshi : Looks even better than the previous pictures we saw. I think the scale is spot on, even if Kid Goku himself is a tad oversized. The stick is a cool accessory, could also use a dirty magazine. Also hoping for some funny faces including a nosebleed face.
Kid Goku : Still looks a bit oversized compared to the adult versions, but I still am convinced that if you pose him right he'll look fine. I'm thinking of posing him sitting crosslegged on the Nimbus Cloud so he'll look shorter. The head will still be oversized but that's due to the chibi look of being a kid. Happy with the accessories, could have used a Korin but hey.
Majin Vegeta : Still looks great. Yes the SS2 hair would have been even better but I'm still very happy about this sculpt with the nice details like veins.
Bulma : Looks amazing, I'm in love. This is one of my favorite looks for her, although I would also have liked a Namek astronaut Bulma and other versions. Guessing we'll get the Dragon Radar as an accessoy, could use some other things too, like a capsule/box maybe.
Also I'm thinking we can definitely hope to see a Dragonball era Yamcha now considering the Dragonball line seems to kick off pretty well. Probably would include a Puar accessory, and I suppose a Dragonball Krillin is also a possibility.
Very happy about all those reveals.
