If anyone wants to actually run into him and get in his path, Hibari will attack them and make them get out of the way to the best of his ability.

In this instance he wouldn't be holding back so there is a high likelihood of serious injury from his abilities. He uses his tonfas and spiked spheres to do most of the damage and can impale people on both, and his other big threat are his spiked handcuffs which look like this.

If they get around someone's limb in this form, he will most likely rip it off.

He will not really focus on any one person and particular and probably run away before they can stop him from causing more destruction.
