Hi! I work for the makers of Bakugan. We have an official Amazon page here: https://www.amazon.com/bakugan

You can get your god son started with the Bakugan Starter Pack, which includes three Bakugan. It's everything he needs to play the accessible toy battling game, including a rulebook. This one has the main character Dragonoid in what most people feel is his strongest form: https://www.amazon.com/Bakugan-Dragonoid-Collectible-Transforming-Creatures/dp/B07GTRC1HB

The Battle Packs come with five Bakugan, and are the best value. Here's my personal favorite: https://www.amazon.com/Bakugan-Cyndeous-Collectible-Transforming-Creatures/dp/B07GTRC1HC

If he's already a Bakugan fan and you're looking to buy him something awesome for a special occasion, Dragonoid Maximus is a huge action figure with an epic transformation, lights, and sounds! He also comes with the Titan Dragonoid Bakugan toy, which is super strong in the toy battling game. https://www.amazon.com/Bakugan-Dragonoid-Maximus-8-Inch-Transforming/dp/B07NPFQBJH

Make sure to only buy things with the Amazon Prime check mark that are "shipped from and sold by Amazon." That's how you know they're official. I hope he enjoys!
