Using the Dia - Battles X - 1 is a blast! Start by exploring its different transformation modes. You can easily change it from one form to another just by following the natural movement of its joints. When it comes to interchangeability, simply find the matching parts from other items in the Diaclone series and connect them securely. As for maintenance, keep it in a dry place away from direct sunlight to prevent any damage to the plastic. Avoid dropping it or subjecting it to rough play, as this could break the delicate transformation mechanisms. And since it doesn't need batteries, you don't have to worry about battery - related issues.
