A Bakupack is your inventory, your storage, the place where you record everything you have. You MUST have one in order to participate in battles. No exceptions.
Simple Bakupack Rules
You may only have the Bakugan, cards, and special shooting skills from your Character Profile you created, those which you bought from the shop, and those you created in the creation section, in your Bakupack. Click here to make your Bakupack.
It's always a good idea to constantly update your Bakupack whenever you get something new. This makes sure nothing is forgotten and that you have everything you need come the time for brawling.
It's recommended that you record all of your matches in your Bakupack so that you have the evidence you need to submit when applying for an evolution/upgrade for your Bakugan and/or Support Weapons. You cannot evolve/upgrade unless you show proof. More information regarding what you need to do for them can be found in this thread[li]
Do not put anything you don't own in your Bakupack. There will be consequences if you use a fraudulent Bakupack for brawling.
Please remember. If it's not in your Bakupack, you don't have it. There won't be any questions asked if you use something that's not in your Bakupack; there will just be negative sanctions imposed on you.
