Spiral Lyre ED145MF

Screw Lyra ED145MF is an Attack-Type Beyblade that appears in the anime, Beyblade: Metal Fury along with Screw Fox TR145W2D. It was released in Random Booster Vol. 8 Jade Jupiter on August 6, 2011 in Japan and is owned by Toby.

Face Bolt: Lyra
The Face Bolt depicts "Lyra", one of the 88 space constellations. It's represented by a vulture or an eagle carrying a lyre, either on it's wings or on its beak. In Greek mythology, a musician named Orpheus was killed by the female follower of the Dionysus, Maenad. Upon his death, his lyre was thrown into a river while the God of Sky and Thunder, Zeus sent an eagle to retrieve the lyre and ordered both of them to be placed in the sky as a constellation. The design features a lyre with eyes on a silver Face Bolt.

Energy Ring: Lyra
Lyra appears to have an unusual appearance, with many curves it gives it a lyre-like appearance. Small circular-like spheres appear on the Ring's top and bottom. The Energy Ring is black with a translucent silver on the Ring's sides with red characters appearing near the spheres. This Lyra Ring is released in black.

Fusion Wheel: Screw
Screw has three distorted wing-like forms, each with an upward curved spike. It was said to have the best Upper Attack of any Fusion Wheel. It is one of the best non-4D attack wheel with lots of Stamina due to something with airflow as shown on the box package. If paired with the correct Energy Ring/Track, Screw may be used in super-effective Attack combos such as Spiral Tempo D125RF.
 * Weight: 34.51 grams

Spin Track: Eternal Defense 145 (ED145)

 * Weight: 3.6g

ED145 features three “hooks” which rotate around the Track freely. Unlike WD145, ED145 can spin freely, they can be used in Defense customisations, such as MF Earth Bull ED145WB; however, the defensive capabilities of this part are not as effective as C145, as it does not absorb hits as successfully. The hooks which rotate are hindered without the mechanism of a bearing, hence creating a force of friction between the hooks and the body of the Track, in turn resulting in less significant damage absorption. Furthermore, it is easy for the low attacker’s Wheel to be caught between the Wheel and ED145, hence causing a lot of recoil and spin reduction to the Defense customization. The free spining feature however does not ensure it will not have any recoil. The "hooks" can be stick on the opposing bey and get stuck. As the Beyblade is spinning and the ED145 is free spining, the Bey can get stuck in rare ocasions and lose some Stamina because of friction.

Good commbination:
Flame Pegasus (III) ED145RS.

Performance Tip: Metal Flat (MF)
Metal Flat has a Flat Tip made of metal, giving it an offensive movement. However, since metal has less friction than plastic Flat Tips, it has less Defense and speed, However, it unlike XF, R2F and WF it can keep the sliding shoot/shot's pattern. It is really powerful in these combos: MF-H Gravity Perseus Counter Mode D125/T125/CH120MF, Lightning L-Drago CH120/T125/D125/125/90/85/100MF. It is one of the best non-4D Attack type Bottoms. The MF Tip will also not wear out like any of the rubber Tips, and has more Stamina than RF/R2F, even easier to control the movement of MF than R2F.
