Yajuu Yajuu no Mi/Miscellaneous Techs

Overview
Over Rio's journey in the Grand Line, he has come across many different species of animals and wild life. Out of all the animals he came across, four of them proved to be useful to Rio with their permission, Rio added their powers to his Devil Fruit and uses them from time to time to throw his opponents off.

These are a list of animals/modes that do not have many named techniques and end up only being used occasionally.

Shell Tortoise Mode

 * Rio’s fourth ability and without a doubt his less used one that he reveals on rare occasions. Rio first learned this ability when he came into contact with a rare species of turtle that were living on Ruan Island. Beast Mode: Shell Tortoise (シェルカメ Shell Kamru) is an ability that allows Rio’s body to gain the resistance, durability, and hardness of a shell tortoise. The main advantage of this fruit is that its defensive capabilities are nearly impenetrable and can survive even the toughest of attacks. Whenever Rio is in a situation that calls for defensive power, the tortoise can provide him with just that and allow him to escape phenomenal damage that would kill a normal man unscathed. Though, the ability does have one noticeable weakness which is the fact that is deters Rio’s mobility. This was evident during his battle with Riku where he was able to block against his sword strikes but he was too slow to keep up with him. Rio doesn’t like being weighed down so he has limited this form to using whenever he needs a quick way to upgrade his defense, otherwise he’d rather just take the attack head on and then counter attack.

This form does not possess any named techniques and is just available for Rio to increase his resistance to damage.

 Sonic Duck Mode

Rio’s fifth form that he obtained during his travels in the Anaphe Desert. Generally speaking, this mode is his most useful one when it comes to land mobility and it also has its uses in combat as well. When Rio came across an injured Sonic Duck, he helped it recover and he befriended it (along with gaining the tremendous speed it possessed).

Beast Mode: Sonic Duck (獣モードソニ Shishi Modo: Sonikku Dakku) is a form that allows Rio to essentially run at such blinding speeds that those without proper training completely lose track of his figure and just witness the dust he creates. This ability along with the already present speed that Rio possessed in his normal state are added together and truly make Rio one of the fastest beings in the world (according to Ike, though this is most likely false). The abilities main power lies in the fact that Rio can transfer said speed to not only his legs but his arms as well, allowing him to throw a flurry of punches and kicks that are almost impossible to dodge or counter.

Stamina plays a huge role in the weakness of this fruit as it drains a great deal of it when in use (as Rio felt himself getting winded when he had used it for such a long time). This is only a testament to Rio’s endurance as he has been shown using the form on several occasions.
