I have a bunch of figures from the various Tamashii Nations lines and wouldn't mind creating listings for them. With that in mind, could an individual "Tamashii Nations" toy line category be created, with the individual lines branching off from there:
Figuarts (D-Arts, S.H. Figuarts, S.H. Figuarts Shinkocchou Seihou, Figuarts Zero as sub-categories)
MonsterArts (S.H. MonsterArts as sub-category, allowing for a "MonsterArts Zero" sub-category down the road if Bandai ever went that route)
Ultra-Act
Super Imaginative Chogokin (S.I.C., S.I.C. Takumi Damashii, S.I.C. Kiwami Tamashii as sub-categories)
Tamashii Effect
Makai Kado
Robot Spirits
Armor Girls Project
Tamashii Buddies
Tamashii Stage
Proplica
(Additionally, the existing Chogokin toy line category could be moved under here, since the various Chogokin toy lines are part of Tamashii Nations; the DX Chogokin line also fits as a new sub-category under the general Chogokin line.)
Many of these lines include figures from various franchises within each line (Figuarts and the mech-based lines most of all) so I figure it'd help to have Tamashii Nations as a catch-all for these lines rather than try and bunch things via individual franchises like Kamen Rider, Super Sentai/Power Rangers, B-Fighters, Marvel, Nintendo, Dragon Ball, Gundam, Brave, etc.
