It doesn't matter what you guys throw at us. Marucho and I will never be beaten; because we've got a solid bond like you two creeps have never seen before! Not to mention, we're fighting with the incredible might of Aquos power!

Radizen (Japanese Version: Luger (ルーガ, Luga?)) is a BakuFusion Bakugan. When combined with Roxtor, he creates Betakor. He is Marucho Marukura's sixth Guardian Bakugan. His Bakugan Battle Suits are Blasterate and Clawbruk, and his Mechtogan is Flytris.



An ancient kappa-like warrior, Radizen transforms by extending his vertical wings to pounce on opponents when they least expect it. His metal sharp horn shoots bullets of energy to tear through his enemies' armor. Radizen fuses with Roxtor to become the mighty Betakor.

Radizen made his debut in Evil Arrival as Marucho's new partner. He first battled against Subterra Luxtor where he used Slam Reef and won easily. He then battled against Gunz Lazar's Reptak where he used Deap Descent causing a sheild to be on him. Reptak uses Grapil buster and break though knocking Radizen out casuing him to lose He then battled Coredegon, Slycerak, Exostriker and Mandibor alongside Fusion Dragonoid and Jaakor. He used Scap Screen to block himself from Mandior's attacks. He then used Luster drain to attack Mandibor with a water ball. Mandibor then used his blasters to attack him which Radizen blocked with his shield. However, his shield was broken by Coredegon and thus he got knocked out. However Dragonoid Destroyer appeared and battled Mechtavius Destroyer. In the end he won thus causing Radizen and Jakkor to win as well.

In Wiseman Cometh, it is revealed that he is not compatible with Dragonoid Destroyer, so Mira gave him Blasterate.

In Combination Impossible, he is upset that Jaakor and Drago are the only ones able to combine. He asks Mira for help but there was not anything she could do. He would then take a trip with Marucho to one of his dad's power plants and soon they are confronted by Wiseman. Radizen was able to hold his own against the two of his Bakugan until they combined. He would then combine with Roxtor and was able to defeat them.

In Enemy Allies, Radizen is seen battling along with the other Brawlers against Wiseman and his Bakugan, they were winning at first but when Mechtavius Destroyer made an appearance he was easily overwhelmed. He fused with Roxtor to create Betakor, he and Magmafury combined their powers but were still no matched for it. Runo sent him a new Battle Suit called Clawbruk which helped him and the other Brawlers defeat Mechtavius Destroyer.

In Gunz Blazing, Marucho summoned him to battle Wiseman but it turned out that the Brawlers were tricked by a Wiseman hologram and didn't end up fighting at all.

In Countdown to Doomsday, he battled the Nonets and their Battle Suits. He used Blasterate and later combined with Roxtor, but ended up being defeated by Mechtavius Destroyer.

In Eve of Extermination, he battled the Nonets and the evil Mechtogan, who combined to form Mechtavius Destroyer. He combined with Roxtor and with the help of Aeroblitz and Magmafury, they were able to break down Mechtavius Destroyer's shield. When all seemed lost, Dragonoid Destroyer used 20% of his power reserve to create Thorak for Jaakor and Flytris for Radizen. With the help of these new Mechtogan, they won the battle with ease.

In Gunz Lives he used Clawbruk to battle Worton who was using a Ventus Clawbruk.

He joined Drago, Reptak, and Jaakor to beat Mechtavius Destroyer in the finale and wins thanks to Dragonoid Destroyer's 100% powers.
