Konosuke is pretty ginormous, it's true. He's 55mm tall, whereas almost all of the other characters are around 35mm tall. He's also one of the more complex minis to assemble. Konosuke comes in the same size box as the starter packs (which normally hold two figures) and he takes up a good deal of room in there. His body is pieces (the legs, two pieces for his "skirt," his torso, arms and then the flags) He's a beautiful mini and you'll certainly be able to pick him out on the field of battle!
Ps. Because of his gigantic stature, Konosuke is unable to Dodge. Just keep that in mind when you're planning out your team.
