Bakutenryu Shin Hayate
AKA: Bakutenryū Shin Hayate, Bakutenryuu Shin Hayate, Bakuten Dragon Shin Hayate, (alternate translations). Shin Hayate is sometimes translated as Shin-Hayate for each of these.
Only Weight Disk name is confirmed, other names are assumed as they were never named by Takara or Hasbro. All four Beyblades are recolors of Bakutenryu Hayate, with no different parts. Parts are named based on the first Beyblade they were released with, Bakutenryu Hayate.
Attack Ring: Hayate Attack Ring
Extremely aggressive design.
Has a huge amount of Smash Attack at the cost of significant rotational recoil - enough to bend the AR back over the SG occasionally.
Recoil due to width plus suboptimal angles on some contact points, but less severe than the Hasbro version due to the lack of poles.
Does struggle slightly more than some similarly powerful ARs against Weight Based Defense due to its recoil making it more likely to Self-KO against them, though this is fairly minor.
Can be helped somewhat by a Heavy Metal Core, though works fine without.
Overall an extremely powerful Left-Spin Smash AR, and one that tends to be quite affordable - if it ends up being legal.
Pretty much the same amount of recoil as in left but with significantly less power.
Not competitive in this direction.
Weight Disk: Weight Ring
A metal ring with 12 notches, only compatible with Hayate Base and Hayate Base (Hasbro) - also note that it counts as a Weight Disk thus cannot be squeezed onto other Beyblades legally.
Lightweight, and can spin a little freely which results in terrible inertia-related issues when launching and in battle, where hits to the weight disk can cause very heavy interruption to spin.
Nonetheless, it is technically not the lightest Weight Disk (that being the soft-edge mold of Eight Wide), and does have an extremely edge-focussed Weight Distribution, which does tend to aid the Hayate Bases to be somewhat less dismal than they might otherwise have been - after all, Mexico's champion for the World Championships did use Tiger Defenser on Hasbro's Hayate Base to win.
No real use, however.
Blade Base: Hayate Base
Flat-underside base with short cylinders extending downwards for attaching figurine. AR and WD both clip onto it rather than normal setup.
Only compatible with Weight Ring.
Tip is a sharp tip used as tip of figurine's tail (and also some kind of crystal in Bakutenryu Zeo and Bakutenryu Aveiron's figurines).
Poor stability, poor LAD, no aggression, and inability to use good parts mean it is a useless part, and the clip on nature combine to make this a spectacularly awful part.
Cylinders make it even worse than the Hasbro version, giving it horrible life after death and early scraping.
Still not as bad as Jumping Base (Trygle).
The Attack Ring is excellent, and one of the most affordable Hyper Aggressive Smash options. While the rest of the Beyblade is not useful, the Attack Ring makes Shin Hayate a great purchase if found relatively cheap.
