>>7093686DD Panoramation aren't too bad but they are pricey before discount if you don't consider the diorama sets they come with. They use modular joints like Figma.
DBZ Shodo is a smaller scale. KR Shodo is popular in the 1/18 general and Toku general threads.
The grand daddy of 1/18 anime figures are Microman. They are kinda fragile though. They did figures of GGG(the humans), Lupin the 3rd, Street Fighter and VOTOMs (that came with 1/18 scopedogs...) In more recent times, they've done Kantai Collection and Love Live! under their Microman-Arts line.
