Pumpking
AKA: Bump King (Hasbro)
Weight: 3.6g
Right spin only
Primary contact points are the wing faces, which have good range and provide decent Smash Attack.
However, due to their angle it is very recoil-prone, and as such falls short of other Smash ARs such as Triple Tiger,
Overhanging design of wings allows it to work more effectively on tall bases (albeit providing a weakness against Circle Survivor Defense combinations), similar to but slightly worse than Triple Tiger.
Thin design makes it an exceptionally fragile AR, however, thus it is not really advisable to use it.
Weight: 12.7g
Light weight with fairly average width and a much more central weight distribution than its successors, notably being heavier than Eight Wide.
Shape causes recoil given its size, which is concerning given its relatively light weight.
Weight distribution does little for any given combination, with Ten Balance being a better choice for the more "average" weight distribution it offers.
Heavily outclassed and almost entirely useless.
Weight: 7.2g
4 Layer System Base with built in Right Spin Gear.
Lightweight
Usable Life After Death
A very stable tip with good stability and survival, making it a good Stamina part.
Commonly used in Survival combos with Ten Balance (as Wide Defense and Wide Survivor have issues with rotational recoil and stability on this base), these are best called Semi Flat Base Stamina Combinations, especially as Heavy-Series Weight Disks are also an option, the most famous of which is 10bBistool.
Outclassed by Zombie Base/SG setups, but still a reasonable option in most tournament situations as Semi Flat Base Stamina Combinations are able to beat most Tourney Filler. However, they lose to almost all competitive combinations and as such do not deserve the accolades they have received over the years.
There is an alternative mold used by certain Takara releases (notably Roller Defenser) which has a thinner tip, making it slightly less aggressive and providing slightly more survival. The difference is largely negligible in battle, however.
Overall
Between the Semi-Flat Base and decent if unfortunately fragile Attack Ring, Pumpking is not nearly as useless as once thought. However, due to the fragility and fact there are multiple better options, it is outclassed, if deserving of some amount of apologies for the Beyblading community.
