Bakushin-Oh
Attack Ring: Down Force Ring
Weight: 3.5g
Right Spin only
Relatively wide (for its time) AR with angled fins which have flat faces and are spaced relatively closely together
Has some Upper Attack, however the slopes are too short for it to be truly effective.
Has some Smash Attack, however the contact points are not well exposed and their flat nature causes noticeable recoil.
With Wide Survivor, can be used for Spin Stealing, however it is quite outclassed here due the recoil on its leading edges, which also means it is ineffective on Wide Defense.
No use defensively (including for compacts) due to the recoil on its leading edges.
Tends to be quite fragile due to the thin design of the fins.
One of the better offensive choices in its own time, but even here Upper Force Ring for example is a better contemporaneous choice.
Overall not terrible, but not a competitive part.
Weight: 15.3g
The most compact weight distribution of any weight disk.
It is worth noting that there is quite a broad range of weights for this Weight Disk, which one should be wary of.
The large corners of its shape result in some recoil when hit, though its compact weight distribution provides some protection against this.
Ten Heavy outclasses it slightly in all aspects of performance due to heavier weight, lower recoil, and Eight Heavy is marginally heavier, with a slightly less compact distribution making it a viable alternative.
Fairly competitive in Compacts and Traditional Upper Attack and a backup choice for Weight-Based Defense and Semi Flat Base Stamina Combos.
Weight: 6.5g
Right Spin Only (Built in Spin Gear)
Very low height allows it to get under things but lack of compatibility with an Heavy Metal Core removes any use for Traditional Upper Attack.
Limited recoil control due to light weight and poor grip.
Somewhat difficult to flower pattern.
Decent LAD means it can be used to some effect similarly to a Semi-Flat Base Stamina setup, though due to its aggression it makes better use of Wide Defense - a viable setup would be this and a Compact or smaller-sized Defensive AR.
While this is not that competitive a setup, it is able to outspin a surprising number of opponents and KO weaker combos, thus giving Flat Base some semblance of use.
Overall not a great part, but usable.
Overall
Heavy is the best part of this Beyblade, and even it is generally considered inferior to its 10-sided successor. The AR is interesting but largely useless, and the Base is not all that great. As such, Bakushin-Oh should only be bought for collection purposes.
