Doobie Wah!

Doobie Wah! (ドゥービー・ワゥ！) is the Stand of Aishou Dainenjiyama, featured in Part VIII: JoJolion.

Appearance
Doobie Wah! usually manifests in the form of a rapidly spinning small tornado with a vaguely humanoid figure inside.

It has two short drooping horns, as well as a single short spike jutting out of the lower half of its face, directly below a single mechanical eye. It appear to have something resembling a crown on its head.

Like Little Feet, it has a long bladed index finger.

Abilities
Automatic Pursuit: Doobie Wah! is an incredibly powerful automatic stand that relentlessly pursues its target as long as they continue breathing. It manifests from their breath and becomes a small but highly destructive tornado capable of easily cutting through flesh.

Aishou must first touch said target in order for Doobie Wah! to activate. This can also be done by coming into contact with their stands. It appears to be the case that Aishou has the ability to sense the movements of his Stand or someone track it another way, which is an ability not usually demonstrated by automatic stand users who are usually unaware of their Stand's actions unless informed otherwise.

Doobie Wah! seems to have the ability to pursue multiple targets, due to it manifesting from both Tsurugi and Yasuho's exhalations after Aishou stepped on their combined stands. .

Its range appears to be limitless, as no matter how far away or how fast the two targets traveled they could not escape it's area of affect.

JoJolion
This Stand first appears when Aishou activates it to attack Tsurugi and Yasuho in a stairwell. It's initial appearance is that of a miniature vortex with the Stand's humanoid figure in the center. From then on it pursues them out the window and across the street, even after the two board a bus and seemingly distance themselves from the building entirely. After making it to a Fire station, the two seem to have outsmarted Doobie Wah! when they don breathing masks with enclosed oxygen tanks, isolating their breath from the open air. This however proves to be irrelevant when it materializes within the mouthpiece and expands, threatening to kill them both until Aishou's untimely demise at the hands of Tsurugi's Paper Moon King, effectively putting an end to the Stand.

Trivia

 * Just as Aishou's status as a Rock Human is similar to the Pillar Men of Part II: Battle Tendency, Doobie Wah's stand ability to summon cutting wind is reminiscent of Wammu's Wind Mode.
