>>8925833Piccolo is about Tien's height in Dragon Ball and at the Raditz saga. In the Saiyan saga he is almost as tall as Nappa. Namek he is almost as tall as 2nd Form Frieza. Android saga he was almost as tall as Imperfect Cell but his arms were ten times bigger. Buu saga he was almost as tall as Super Buu. So it's possible he stopped growing after Saiyan saga or he kept growing and Super Buu was enormous.
The Figuarts works very well for the Raditz and Dragon Ball Piccolo for height but not the gi since he doesn't get the V-cut until Androids. I hope one day we get the big Piccolo we deserve though.
