Yajuu Yajuu no Mi/Fusion Beast Techs

Overview
During Rio’s fight with Luis Von Delter, Rio had pushed himself to his breaking point and was beyond his limit as Luis was proving to be the toughest opponent he had ever faced. Rio then realized that he had never tried to use two of the powers he had gained and thought that he might be able to pull it off. Even though the damage to his body was immense as he wasn’t used to it, the results were catastrophic as he was able to plow through the The Tower Of Judgment while continuously assaulting Luis all the way to the top.

Fusion Beast Mode (融合モード ック Yugo Modo) is a mode where Rio combines the abilities of two other modes and utilizes the benefits from both of them. The mode is extremely dangerous as using it seems to take a great deal of stamina to control (as Rio was panting heavily after he had entered the mode) and while it does grant Rio magnificent powers, it comes at the risk of slowly losing his consciousness over to the animals he touched.

Techniques
The first time we saw this mode being used was during his fight against Luis Von Delter. Finally taking the battle seriously, Rio combined the raw strength of the ox and swift speed of the Duck to create the Sonic Ox Mode (ソニックダ  Sonikku Oxuh Modo) that allowed him to move at super fast speeds while at the same time, using the strength of his ox imbued fists to decimate anything in his path. Needless to say, the results were indeed worth it as it was able to break through Luis’s impenetrable defense and win him the fight.



So far, there has only been one listed technique for this mode.


 * Delta Storm (サイクロンハンマー  Dellta Storumu): One of Rio's most powerful techniques that won him the match against Luis Von Delter. Following up his brilliant counterattack, Rio summons all of his available strength and stamina and pours it into his last assault that enables him to unlock a new level of power that surpasses his old limits. This technique uses the speed of the Sonic Duck to create an uncountable amount of punches and kicks at the enemy and the power of the Ox that makes each one more devastating then the next, resulting in a flawless combination technique.
