But there's precedent for discussing them, okay. Well at least a little.
Bakugan is back! Picked up this guy just to see what the new stuff is like and I'm digging it. This guy's tail is beefy with super-strong springs, so he does a flip as he opens and lands in this crouching pose. The rectangular metal-lined arena cards have been turned into little hexagonal cards, and instead of getting your figures to stop on top of the cards your goal is to grab them in passing, and your figure flips over the card and reveals its bonus. This Garganoid winds up with the card on the end of its tail.
As for backward-compatibility, the new engineering makes them work poorly with the older metal "gate cards" because they get in the way of flipping over. They don't "stand" by the definition of the old rules. Also, since the new ones don't have attribute symbols, technically by the old rules they can't get anything from the old cards anyway. There seems to also be a full TCG aspect of it now that I haven't checked out. It looks like there's a game with just rolling the figures for a quick game or TCG rules for a longer game?
Update, only the "Ultra" Bakugan do the auto-flip, the regular ones just open like classic Bakugan. And I just noticed for some odd reason the entire Subterra attribute has been removed.
These little guys had never been a thing I was really aware of, but my son got some recently and I was shocked by how amazing the better ones are.
Some of them are rubbish, but some of them pack surprisingly fun little transformations inside their spring-loaded spheres. At their best (which seems to mean "a few of the Ultra-class ones"), they're a hell of a lot better than any Transformer I've ever seen that tried to turn into a tiny ball - they're certainly far more impressive than the RID15 minicons or your average Botbot.
The "game" you can "play" with them seems like pointless rubbish, and I assume the various anime series are too. But I was really astounded by how great the best of these are. (NOTE: not all bangerganks pictured can be classified as "best")
Admittedly, "can't transform them without a magnet" is a fairly serious limitation.
