Tatsu Tatsu no Mi, Model: Fire Dragon

The Tatsu Tatsu no Mi, Model: Fire Dragon is a Mythical Zoan type of Devil Fruit, in which the user is able to transform into a hybrid or full version of a Fire Dragon. Tatsu meaning “Dragon”, in both Viz Manga, and the FUNimation dub called the Dragon-Dragon Fruit, Model: Fire Dragon, which was eaten by the Riku Dragion.

Strengths
The major strength of this fruit is as shown by Riku, beside to transform into full or hybrid Fire Dragon is that increases many of his attributes such as strength, speed, edurance and many attributes. Riku can also generate a feild of flames that he can control in any situation. Another strength of this fruit is that when he turns into a hybrid Fire Dragon is that on his skin a Dragon scale creates which protects him from multiple aspects. These scaled are said to be as hard as diamond and as string a as carbyne. As well when Riku turns into a full Fire Dragon his opponent would think that he can't move fast enough with that big weight, but another strength is that he can move much faster than he was still in his human form. His fire is hotter than normal fire. This was shown when he was able to stand up to Akainu's Magma punch. He is completely immune to plasma, shown where he took a direct attack from Enel with no injuries, also shown when Kizaru sent a blast his way, he took it head on, absorbing it. The only lightning based devil fruit Riku can not absorb, unless in Storm Dragon Mode, is the Tori Tori no Mi, Model: Thunderbird.

Weaknesses
Aside from standard Devil Fruit weakness user suffers when fighting against any form of liquid user, any form of liquid, and anything that resonates from heat, such as smoke and steam, (although in some forms he smokes and steams contradicting his own weakness).
