Highway Star

Highway Star (ハイウェイ・スター) is a stand featured in Part IV: Diamond is Unbreakable.

Abilities
Speed Up!: From what is seen, the stand has the ability to run at extreme speeds. It was shown easily reaching up to (though is only able to reach up to) 60 km/h. The range of the stand seems limitless, since the user was actually in the hospital the entire time the stand was shown chasing Josuke and Rohan around town.

Dried Up!: Its main ability is to suck nutrients from its victims and transfer them to its host, giving the host heightened senses (most notably a heightened sense of smell). When it sucks out the nutrients, the victim's skeleton can be seen, and they are left severely exhausted and unable to move.

Split Body: Highway Star can section itself into many parts as it flies at its extreme speeds, breaking apart in flat horizantal segments and moving, then reassembling piece by piece. This allows Highway Star to do things like slip though narrow passages or do large scale multi angle attacks by striking with all its pieces at once.

The Room: Highway Star seems to have a rather odd ability to attract spiritually aware victims by creating a room in a wall to lure them in. This room was only noticed by Rohan Kishibe and Josuke Higashikata, both being stand users, and originally lured Rohan, presumably by using his memory of and desire to track Yoshikage Kira. Anyone who enters the room is targeted by Highway Star, who begins to track and pursue them with its sense of smell to absorb their nutrients. The details of the execution for this technique are unknown.
