Flash Leopard 2
AKA: FL2 (Abbrev.), Flash Leopard II (Hasbro)
Weight: 5.5g
Right Spin:
Lacks effective contact points in this direction
Ineffective, somewhat recoil prone, and overall not very useful.
Left Spin:
Solid Smash Attack without much recoil from the well-angled regular contact points and the thick, if poorly exposed back of head parts which offer additional power at the cost of slightly more recoil.
Slopes offer a little extra destabilization in addition to that caused by fast moving opposite spin Beyblades in general (which combos using Panther Head are likely to be against most opponents).
Range is somewhat limited, and Ten Wide is likely a better WD choice than Wide Defense because of this, but even with that limitation this has very little tangible effect on performance.
Overall, a competitive part for Left Spin Smash Attack
Weight: 16.1g
Heaviest legal Weight Disk.
Compact size and weight distribution makes it excellent defensively but not useful for Attack
Excellent for sustaining RPM – helps with defense, grinding, force smash, upper, and also defending against the last three.
Primary choice for Compacts, Traditional Upper Attack, Weight Defense, Circle Survivor Defense, and a competitive choice for Force Smash and Driger V2 combos.
With faster Attack Blade Bases (i.e. Defense Grip Base (Tip Inverted) and SG Grip Change Base Tip setups), Ten Heavy can be used without loss of speed, and its high weight becomes quite useful with Attack Rings such as Square Edge and Hayate Attack Ring, improving their rotational Smash characteristics however the reduction to the flywheel effect otherwise provided by Wide Defense or Ten Wide tends to result in more recoil KOs. It is nonetheless an acceptable option.
Overall a very versatile Weight Disk and a must-have part, outclassing both Heavy and Eight Heavy in all aspects, as well as being generally superior to Heavy Attack.
Spin Gear: Neo Right Spin Gear (North Magne Version)
Weight: 1.15g ea (total 2.3g)
Generally preferred to regular Right shells due to being compatible with all SG-Compatible bases, in particular for being compatible with Neo SG Cores and the Heavy Metal Core.
This means they are a necessity for Compacts, Weight Based Defense, Force Smash, Traditional Upper Attack and Driger V2 Combinations, at least aside from the rare occasions Left Spin is desired for one of these types, in which case Neo Left Shells are preferred.
Overall a crucial competitive part, but thankfully exceedingly common.
Note: When used in an SG, any Magnecore is listed as "Magne Version" with no specification of the polarity. The polarity is listed in PlasticsDB Part Names for clarity.
Weight: 3.3g
Only compatible with Neo Shells.
Magnet polarity has little impact outside of Magnecore Stadia.
Only real effect is when using a magnetized tip (Magne Flat Base Tip and Customize Grip Base Tip , which repel North Magnecores) or Magne Weight Disk (which can be flipped over as needed anyway), and even here the effect on performance is negligible, it just makes assembly slightly more difficult and puts a bit more strain on the Base Clips.
Only real effect is weight: not as overwhelmingly heavy as a Heavy Metal Core, yet with enough weight to help a little with recoil, Magnecores tend to be a decent choice if trying to control recoil on Attack types, with Heavy Metal Cores generally slowing the Beyblade down too much on some Bases. That said, this is generally a last resort outside of SG Metal Flat Base (Gaia Dragoon V Version), where it is often around the right weight for a good balance of recoil control and movement speed.
Defensively, it is outclassed by the significantly heavier Heavy Metal Core, however it is the next best thing, and still works okay for Defense/Compacts, albeit not nearly as well as an HMC due to the significant difference in weight
In Magne Stadia, North Cores are intended to be defensive (attracted to magnets in Magnecore stadia, thus staying in place).
Weight: 7.6g
Tall and bulky yet still vulnerable to Upper Attack due to the long tip section.
Tip has bad stability, no movement and limited defense due to its low friction and tendency to tilt exposing the Beyblade to hits at an angle, making it quite poor.
Poor LAD due to the large underside gaps and spikes, which coupled with the poor stability of the tip makes for extremely poor performance.
Comes with some of the heaviest base clips of any Beyblade (~0.46g each), though SG (Auto Change Version)'s are slightly heavier (however, given the similar weights, there is likely some crossover). Due to their large size and the fact they protrude greatly on practically every Blade Base, and that they are only 0.1g heavier than standard sized clips, this serves no practical purpose.
One of the heavier Blade Bases in total, but not heavy enough to be useful for Weight Based Defense given the terrible shape and tip.
Overall not a useful part, outclassed by even Metal Sting Base - and the relatively contemporary Customize Metal Sharp Base is far, far ahead.
Overall
While it has a good Attack Ring and a useful Weight Disk and Spin Gear, Flash Leopard 2 faces a lot of competition from more readily available Beyblades, in particular Metal Driger, with an AR that shares an identical niche, the same Weight Disk and a more useful and completely unique Core, and while the fact Flash Leopard 2 comes with Neo Casings is a positive, so do many other Beyblades that have a lot less competition. Overall, Flash Leopard 2 isn't a bad buy, but it's generally not necessary.
