Rowen looked at the man and woman struggling futilely within his smoke constructs and issued a mental command.

"Check Traits."

——

Mr. 5 Traits: Bomb-Bomb Fruit (Deep Purple): Bomb Human. Can turn any part of the body into a bomb.

Miss Valentine Traits: Kilo-Kilo Fruit (Deep Purple): Kilo-Kilo Human. User can freely manipulate their own weight between 1 kilogram and 10,000 kilograms. Can float like a feather or crush enemies with astonishing weight.

——

Two relatively weak Paramecia Devil Fruits.

Especially the Kilo-Kilo Fruit.

Its power was vastly inferior to Shiki's Float-Float Fruit, It could only alter the user's own weight, with a fixed upper limit and no potential for further growth.

And because attacks required physical contact and needed an umbrella for directional control (like Miss Valentine used), they were easily dodged. On its own, this fruit's power was mediocre at best.

But in Rowen's hands now—it was a completely different story.

Rowen currently possessed the Smoke-Smoke Fruit.

The biggest drawback of the Smoke-Smoke Fruit was its lack of offensive power. Against weak opponents without Haki, its ability to bind and suffocate was potent. But against Haki masters, it served primarily as a support tool.

However, combining the Kilo-Kilo Fruit's ability with the Smoke-Smoke Fruit changed everything.

Infusing the Kilo-Kilo power into his smoke could allow Rowen's smoke form to reach a weight of ten tons! Combined with Haki, this could completely compensate for the Smoke-Smoke Fruit's current offensive shortcomings.

The Bomb-Bomb Fruit could also synergize with the Smoke-Smoke Fruit.

The Smoke-Smoke Fruit could fill the battlefield with smoke, disrupting enemy Observation Haki.

Devil Fruit powers and Haki didn't necessarily counter each other; powerful abilities could shatter Haki attacks, and naturally, they could also interfere with Haki perception.

Consider Sanji's dream Devil Fruit, the Clear-Clear Fruit. Its strength lay in rendering the user completely invisible—including their presence, emotions, and anything else detectable by Observation Haki.

Unless an opponent's Observation Haki far surpassed the combined strength of the Clear-Clear user's fruit and their own Haki, perceiving their movements and presence would be impossible. Otherwise, why would someone of Shiryu of the Rain's caliber choose that ability?

How else could Shiryu successfully land a sneak attack on someone with Garp's level of Observation Haki?

While filling the battlefield with smoke didn't interfere with Observation Haki as effectively as the Clear-Clear Fruit, it still had an effect, albeit mostly supportive.

But adding the Bomb-Bomb Fruit changed the equation entirely.

The Bomb-Bomb ability could be infused into the smoke, turning it into explosive smoke! Enemies caught within the smoke field would suffer unavoidable, omnidirectional explosive attacks!

Acquiring these two Paramecia fruits at this stage was a decent haul.
