The Gluttony Fruit

[LV2: Gain some of the effects of fruits, can digest most things, and acquire some of their properties after digestion. Requires 3 million Berries to permanently unlock.]

[LV4: Fruit Deep Development, can devour non-physical elemental substances such as 'clouds', 'wind', and 'slashes', but after devouring, it can only use the substance and cannot obtain its elemental properties. Requires 100 billion to permanently unlock]

[Note: It is possible to fuse living and non-living things, allowing the living thing to acquire its characteristics, but it can only possess one non-living characteristic at a time.]

[LV5: Fruit Awakening - Devouring Domain: Creates an all-consuming domain around the body, devouring everything within its range and acquiring its properties. It can devour things with lineage factors, but the acquired ability level will be weakened to LV1. Requires 200 billion Berries to permanently unlock]

"Comfortable."

Roy sat on the edge of the bed, feeling as happy as if he had downed three glasses of iced cola.

That's right.

The Gluttony Fruit—a Devil Fruit belonging to Wapol.

At the same time, it is also one of the world's top fruits in Roy's knowledge.

Its mechanism of devouring everything and turning it into its own is so powerful that it can even fuse living and non-living things, and can even devour elements and slash non-physical matter. It is extremely strong in every aspect. Of course, its only weakness may be that it encountered a weak master.

According to the original work, this fruit should have been one of the abilities that Blackbeard chose for himself, but because Wapol ran away from Drum Kingdom at the time, Blackbeard failed to achieve it.

This can also be seen from its price and capabilities—its enhancement price exceeds that of the Slice Fruit, making it the most expensive of all the fruits currently owned by Roy.

As for its abilities, once awakened, this fruit can absorb the abilities of other Devil Fruit users. Although it is a weakened version, its uniqueness is unparalleled in the entire One Piece world!
Of course, this ability is not very meaningful to Roy—after all, he already has the 'Devil Encyclopedia'.

But the key issue is...
"With the Swallow Fruit, we have enough for the refining of the Pluto Alloy."

Yes—this fruit is the key that Roy believes can replace the 'Mother Flame' to complete the forging of Pluto Alloy.

"Next, all we need to do is find enough materials and a suitable buyer."

Roy thought to himself – he already had a preliminary plan for the materials and buyers for refining the alloy.

But for Roy, there was more to it than that.

What truly surprised him during this trip to Drum Island was...
【Human Fruit】

[Fruit Ability - Can transform into a 'human' after consumption]

The fruit that Chopper ate was what surprised him.

In fact, the fruit itself is of little use—its effect is to turn you into a human, which is of almost no use to humans.

Therefore, before Roy traveled through time, this fruit was jokingly referred to by some as the 'Human Fruit - Commoner Form'.

Its price is also very cheap. Roy took a closer look and found that even if it is strengthened to the LV5 awakening level, this fruit only costs 1 million Berries.

[LV5: Devil Fruit Awakening - Human Limits, grants the unique 'transformation' ability of a Devil Fruit, granting the strength and mental capacity of an ordinary human to the limit, and allowing the user to maintain human form under any circumstances]

And that's the most crucial part.

In terms of combat power alone, this fruit is obviously unique. The only meaningful enhancement for Roy might be the enhancement of his mental abilities.

But
"It can maintain its human form under any circumstances."

This trait after the fruit awakened gave Roy a bold idea.

"How about giving it a try?"

Roy murmured to himself, then tried to activate the ability he had always been hesitant to use.

"Buddha Form - Transformation!" His body began to swell.

An unprecedented golden glow began to emanate from his flesh and blood.

He could feel the surging power within him at that moment.

Yes, although he has almost always used only the shockwave ability of the Buddha Fruit.

But don't forget, the Buddha Fruit is a genuine Mythical Zoan-type Devil Fruit.

Its ability to enhance physical strength is no less than that of the Ancient Zoan Dragon Fruit, and may even be stronger.

"Buzz!"

And just as Roy was about to transform into a giant Buddha with a golden body…

[Human-Human Fruit has been upgraded: LV1→LV5]

[Fruit already loaded: Strength Fruit LV3 → Human Fruit LV5]

With a thought from Roy, the fruit was replaced in an instant.

It was at that very moment that his body suddenly froze.

The golden light stopped flowing, and Roy's body also stopped expanding, quickly returning to its original shape like a deflated balloon.

but…

"really."

Feeling the power within him, Roy's voice grew increasingly excited.

"My current strength and physical condition are still the 'beast form' of the Buddha Fruit, that is, the 'Golden Buddha' state."

"But because of the awakening effect of the Human-Human Fruit, my body still retains its normal human form!"

After confirming this, he then tested the effects of Ancient Zoan Devil Fruits and Logia-type Devil Fruits.

Ultimately, he also came to his own conclusion.

When equipped with the 'Human-Human Fruit LV5', he can maintain his human form while using Zoan-type beast transformation and human-beast transformation, and gain full access to Logia-type Devil Fruit abilities.

In other words, even though his hands had been heated to a state almost like real magma, structurally he was still 'human'.

Of course, abilities like the wings of a pterosaur and the 'elementalization' of a Logia-type Devil Fruit, which require separation from the human body structure, cannot be used in his human form.

Even so, it was enough to excite Roy.

Because of the characteristics brought by this fruit, he can use his abilities more recklessly to a greater extent!
"Not bad, not bad, I'm going to find Teacher Zefa to practice my boxing skills now!"

But just as he opened the door, wanting to go find Zephyr and try out his new form...
"Boss!" *2
He then saw Hans and Far below, waving at him.

At this moment, both of them looked quite excited: "Boss, we were just about to call you. We have good news!"

"good news?"

Roy looked at the two of them with some confusion, and then heard them say, "It's Hanafuda—the two Devil Fruits that guy owed us have been delivered to Port Oris!"

Upon hearing this, Roy raised an eyebrow.

"Oh?"

As mentioned before, the two billion Berries that Hanafuda had used to redeem himself had already been allocated to him by headquarters after Roy returned.

Roy gave a portion of it to his brothers in the detention force, especially the two wounded men from before, while he naturally kept the rest for himself—after all, his previous enhancement of the Buddha Fruit and Door-Door Fruit had indeed caused him to suffer a serious loss of savings.

And now, Hanafuda has surprisingly delivered the two fruits she promised so readily.

Roy was naturally quite surprised by this.

"Let's go check out the port!"

　The Gluttony Fruit allows users to gain powers by eating other Devil Fruit users; this is a plot point from the theatrical film.

　　Although the Winter Island theatrical version itself has many contradictions with the original work, it is, after all, an official theatrical version, so let's consider it part of the setting for now.
