Changes

Radizen made his debut in ''[[Evil Arrival]]'' as Marucho's new partner. He battled against [[Gunz]]'s [[Reptak]] and lost. He then battled [[Coredegon]] and his [[Mechtogan]], losing again.

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.
