Using your THE GATTAI Fighbird is super easy. First, transform it from Fire Jet to Fighbird. Just follow the natural movement of the parts to complete the transformation. Then, you can combine it with the Flame Breaster. Attach them gently to make sure they fit well. For the Landing Gear, you can simply deploy it without changing any parts and roll it around. When it comes to the Flame Breaster's dual cannons, you can move them back and forth to make it look more dynamic. In humanoid form, slide the Flame Sword into the nose cone of the Fire Jet for storage. To use the Yutaro Katori android form figure, transform it into Fighbird's core and combine it with the mecha. As for maintenance, keep it away from sharp objects to avoid scratches. Also, don't expose it to extreme temperatures or humidity. If it gets dirty, you can use a soft, dry cloth to gently wipe it clean. Have fun playing with your figure!
