Sorry this one is a bit late, but it's here. Good luck, everybody!

Edit: Also my bad that this says III instead of IV, typo lol

Ryu Ryu no Mi, Model: Stegosaurus

This Ancient Zoan type Devil Fruit allows the user to become a full Stegosaurus or Stegosaurus hybrid at will. Being a dinosaur, the user is granted high defense and strength, but is quite slow. The spikes on the tail work like a drill, because that's super accurate. Also incredibly accurate is the ability for the user to launch the plates on their back, which explode. The user's farts are also really potent.

Techniques

Atomic Fart the user farts, which can poison people nearby. This technique is pretty powerful unless the target is resistant to poison (like Luffy) or wearing a gas mask

Diamond Missile the user launches the plates on their back at the target, which explode on impact. Very powerful against slow-moving opponents

Drill Tail The user's tail spins like a drill, dealing heavy damage to anything. Works especially well against other ancient zoans

Ryu Ryu no Mi Model: Ankylosaurus

Type: Ancient Zoan

Transformations:

Hybrid Transformation- In the hybrid form, the user retains their human intelligence and some dexterity while gaining many of the Ankylosaurus's physical traits. This includes:

• Partial armored plating along the back, shoulders, and head.

• A smaller but still powerful clubbed tail for offense.

• Spikes protruding from the shoulders and back for defense.

Full Transformation- The user can transform into a full Ankylosaurus, gaining the tough, armored skin and massive club-like tail. In this form, the user becomes highly resistant to physical damage due to the Ankylosaurus's natural armor, and their tail becomes a devastating weapon capable of smashing through obstacles and opponents.

Abilities:

All Encompassing Defense (Hōkatsu-tekina bōgyo, 包括的な防御)

When in danger, the user can hunker down, using their thick hide and spiked armor to shield themselves from attacks. This defensive form can allow them to block attacks from multiple angles.

Giants Blow (Jaiantsuburō, ジャイアンツブロー)

The user’s tail can be used to deliver a devastating blow, similar to a sledgehammer. When fully transformed, the tail's club can crush boulders, destroy buildings, and severely injure even the toughest opponents.

Smash of the Heavens (Sumasshu Obu za hebun, スマッシュ・オブ・ザ・ヘブン) By slamming their tail into the ground, the user can create shockwaves, destabilizing the environment around them and knocking opponents off balance. In some cases, they can create fissures in the ground or send debris flying to disorient foes.

Berserker (Bāsākā, バーサーカー) (Awk Technique)

The user temporarily increases their Strength and Stamina at the cost of nearly losing their sanity

Weaknesses

-SeaWater (duh)

-Ariel Attacks (while it defends well against land, it cant do nuthin against air attacks)

-Attacks from below (The stomach is quite soft so a well placed attack from below will effectively eliminate the user)

-Limited speed (The Anklyosaurus was a slow dinosaur so therefore the user will not be able to move as fast per se)

Kuma Kuma no Mi: Model, Giant Short Faced Bear

The Kuma Kuma no Mi: Model, Giant Short Faced Bear is an Ancient Zoan-type Devil Fruit which allows the user to transform into a short faced bear hybrid and full short faced bear at will.

Strengths

This fruit allows the user to transform in full or hybrid short faced bear at will. The full form of this Devil Fruit gives the user a massive size increase. As an Ancient Zoan, this fruit grants the user much greater strength compared to regular Zoans. The hybrid form grants the user a much taller size compared to the full Zoan transformation while the chest and lower jaw appears to be the user’s with the limbs, neck, and head of the bear.

Despite the user’s size in both forms, the user is extremely fast for their size with their physical capabilities being extremely powerful as well.

Like other Devil Fruit users, the user of this fruit is capable of awakening their Devil Fruit. Their Devil Fruit awakening gives the user a boost in physical capabilities and faster healing and appears to have either a black or white band around them if they are in control of the awakening.

Weakness

The user suffers from the standard Devil Fruit weakness.

Unique Techniques

Rock Claw: The user charges at the opponent in either form and scratches the opponent with their large and powerful claws dealing massive and potentially fatal damage. This technique can be strengthen with armament hardening

Dark Lariat: The user in their hybrid form coats either arm with advanced armament haki and charges at the opponent with extreme speed and hits the opponent either at their neck or chest area launching them with great force dealing massive damage.

Over Lariat: A different version of Dark Lariat. The user uses Geppo and puts themself at a high distance and eventually goes back down at an extreme speed while using Geppo to increase their attack power while coating either arm in advanced armament haki and hits the opponent while in the air at their neck or chest and launches them down with extreme force dealing great damage to the opponent and to the surrounding area. This technique only works while the opponent is off guard while being in the air.

Thunder Hammer Bellow: The user coats their giant hammer with armament and conquerors haki and jumps into the air while coming down and spinning at a fast pace eventually slamming the hammer onto the opponent dealing a massive amount of damage. This attack can be increased in damage when the user applies both advanced armament and conquerors haki to the weapon.

Thunder Crash Debris Slide: The user coats their giant hammer with advanced armament and conquerors haki and hits the ground with massive force dealing great damage to the area eventually hitting the giant chunks of debris with the hammer and launching them at the opponent. The technique requires great mastery over observation haki and requires the user to hit the debris at a really fast pace before the debris falls.

After reading over everyone's submissions (and considering the fact that people who have previously won can no longer be considered the winner of future contests), I'm proud to announce @Commander Linus as the winner with the Ryu Ryu no Mi, Model: Stegosaurus! Congratulations

Yay

Damn congrats

Congrats
