Oasis

Oasis (オアシス) is the Stand of Secco featured in Vento Aureo.

Appearance
Unlike most Stands, Oasis takes the form of a wearable suit, like White Album. Oasis covers most of Secco's body, only leaving the eyes exposed. It is covered in many sets of parallel stitches.

Its design is made to look like a snake skin.

In the colored manga and PS2 gideo game adaptation, Oasis is presented as light brown.

Abilities
Oasis is rare among Stands in that it appears as a suit for Secco to wear and fight with. Its power to turn rock into mud and its enhancement of Secco to the point where he can overpower Sticky Fingers makes it a dangerous Stand to fight at close range.

Green Day and Oasis form a deadly combination of Stands as Secco can force targets to sink underground, accelerating Cioccolata's mold's growth.

Ground Liquefaction
Oasis' main power is to make solid ground, among other things, into mud.

To liquefy the ground, Secco must touch the rock to melt it and if he loses contact with any chunk of it, it immediately hardens. The liquefied ground has the consistency of mud but also has elastic properties, enabling Oasis to be used in conjunction with Cioccolata's Green Day in order to make victims sink into the ground and have the mold of Green Day rot their flesh. Secco's power is theorized to have a 10 meters range at most by Mista.

The main use of this ability is to allow Secco to travel underground by swimming through it, keeping him both hidden and safe from attacks and allowing him to move at a faster pace than someone could run on the liquefied ground. Secco cannot see while traveling underground, however, and so relies on his hearing to help him with tracking his enemies.

With this power, Secco can also sink whole structures like a set of stairs into the ground. Moreover, he's able to weaponize this ability: by flinging the liquefied ground, Secco is able to turn it into harmful projectiles that injure his enemies (the liquid ground hardens instantly). Secco's main mode of doing this is usually holding it in his mouth, then spitting it so as to keep his hands free. Depending on his method, he can spit rocks with enough power to deflect bullets, or spit a load of mud high into the air to rain down as deadly spikes.

Oasis also allows Secco to augment the speed and power of his punches. The liquefied ground has elastic properties. By pushing his elbows into liquefied ground, he's able to rebound his arms off the surface and rapidly spring his fists toward his target as a result. This ability was described by Bucciarati as a "boxer bouncing off the ropes as he punches", and because of it, Secco was able to overpower a close-ranged Power-type Stand like Sticky Fingers.

Oasis can also melt the human body if someone stays underground near Secco or through direct contact with him.

Physical Enhancement
Oasis enhances Secco's physical abilities, mainly his power and speed. While wearing Oasis, Secco can effortlessly dodge several bullet or even deflect them with his punches. His kick is faster than Sticky Fingers' punch and he can punch the softened ground to create a shockwave powerful enough to make several cars flip and destroy a a section of the Coliseum.
