Full disclaimer : I love all evolutions of Luinor/Longinus in the anime and they are also crazy a strong in real life too.
I bought this beyblade coz it's cool and I like dragons and I'm surprised to say it's actually pretty neat. It's not an original Bloody Longinus 13 Jolt. However, I feel the replication of it is neatly done. It feels solid and I feel it's viable for battle.
I do find some problems such as the metal parts of the Layer and Disk are very unpolished and the Disk feels loose hanging from the Layer and the Driver says it's Jolt but it has no rubber, basically making it Spiral ( Spiral is actually a very decent Driver )
On the plus side, the delivery is on time and the bey is all-round great, the plastic parts feels genuine and the dragon style is intricate. The Layer is large and has better reach than most other beys. Though being a replica it actually managed to burst my original Fafnir F3 and Luinor L3.
Bloody Longinus is actually one of the best left-spin Burst Beyblades in the metagame. While its predecessor Nightmare Longinus/Luinor L3 has more weight and thus attack potential, it can't support Disks, something Bloody Longinus can support, making this bey more customizable and thus ultimately better.
For the price, I must say it's a must-buy if you love beyblade.
