So we know that Queen is based on Obelix. Obelix best friend is Asterix, who they usually go on adventures together to find the missing ingredients Getafix asks them for.
Based on what we know from the story so far, we can somewhat infer that Vegapunk is based on Getafix, the genius who knows all the secrets of the magic potion. The magic potion is the “lineage factor”. Getafix is also an old man, which we know Vegapunk to be (Sentomaru always called him old man).
Vitalstatistix is Vinsmoke Judge the leader of Germa. He constantly uses “human shields”, and in envious of Vegapunk (maybe insecure as Vegapunk has a bigger reputation).
As for Asterix, I think this may be Sentomaru, we know Sentromaru works under Vegapunk and has strong fists. I mentioned in another theory, that Sentomaru may have provided Vegapunk with Kaido’s lineage factor to make Momonuske’s devil fruit. Getafix usually gives missions to Asterix and Obelix to gather “ingredients”.
In addition, I believe that Vegapunk is the one who gave Queen his mechanical arm. We know that Vegapunk is from Karakuri Island. This comes from the Karakuri puppets – traditional Japanese mechanized puppets or automata that are used for entertainment. There are 2 main kinds of them.
The first is Butai karakuri or stage karakuri which were life-sized dolls designed for public performances such as theaters. The second is Dashi karakuri or festival car karakuri which were large mechanical dolls used in religious festivals. The second one is very reminiscent of the vehicle queen arrived in in Udon before his stage performance, and it is similar to the platform which Apo and Queen were performing on.
I think this is a play on Queen’s character by Oda, and shows that his arm may be made by Vegapunk, the man from Karakuri Island.
