Shieldon is a small reptile with a yellow body. It has white toes and bears a white bump on its back. Shieldon has a dark-gray oval-shaped face. Shieldon may be ancient relatives to the Aron line due to identical typing and partially similar movepools, especially the ability to learn Metal Burst.
When Shieldon appears, it'll duck its head and charge forward aimlessly plowing through any opponents in its path. Shieldon will mindlessly smack into any walls or obstacles in its way or run straight off the stage before disappearing.
