Einstein MS was released by Hasbro as Hopper Attacker.
Bit Protector (BP): Heavy Metal Emblem
The Bit Protector of this Beyblade is Heavy Metal Emblem. It is the first mould verson of Bit Protectors.
Attack Ring (AR): Metal Spring
- Weight: 16 grams
Metal Spring is a triangular shaped AR. Its ABS capsule is in the center with the metal around the edge, which means that the metal is the part in contact with the opposing beyblade for the most part. The edges of this beyblade are jagged, though they don't extend far. There are also three "heads" that allow for some smash attack, though it also results in some recoil. This AR is also very small, and although it isn't very heavy, it can work well in compact customizations, especially more aggressive ones.
Use in Smash Attack Customization
Metal Spring has many small extensions that allow for smash attack and although it can have some recoil, a rubber flat tip can help reduce it. Here is an example:
Use in Compact Customization
Metal Spring is also small, which allows it too be used in compact customizations, and although it is very outclassed by Metal Ape (Magical Ape MS), it can be viable in more aggressive compact customizations, where Metal Ape (Magical Ape MS) doesn't perform as well.
Weight Disk (WD): Circle Heavy
See Circle Heavy.
Running Core (RC): Spring Core
- Weight: 3 grams
This RC is very tall and has a spring inside that lets the tip bounce on the launch. Its tip is a plastic sharp. This means the beyblade using Spring Core will be very vulnerable to attack as well as have very poor balance. So, this RC has no competitive use, but can be fun to use just for the gimmick.
