Acid Skill: Many Hollow's have been known to display abilities that seem to cause acid-like damage to opponents. For example, When a Hollow grabs a Human with their hands, the spot where the person was grabbed is shown to get burned as if acid were poured onto it. Thus, as the years seemed to have progressed, this Acidic Touch has been advanced to the point where it effects all beings and gets stronger with each level. More advanced Acid Users will even be able to create varying effects for their acid such as with Custom Cero's.

Garganta: Garganta IS how Hollows and Arrancar move to and from Hueco Mundo. Though, due to recent discoveries by Zin Yuudeshi, it has been advanced to where it can even be used for speed-like purposes. For example, some advanced Hollow are now able to use this trait to form Garganta's for combat uses such as trapping attack's in them, unleashing hidden attacks or modifying the path that leads to Hueco Mundo to different realms. Therefore, as you increase your Garganta skill, these skills will come to your Hollow. Along with that, for each higher skill level, you will eventually be able to summon them much more quickly to use them for combat or defense.

Cero/Bala: Cero's are highly explosive energy-based attacks that can be shot off from almost any part of an Arrancar or Hollow's body. This is something the Arrancar and Hollow are known and feared for as some cero's have been displayed to wipe entire villages or town's clean off the map. To a lesser extent, however, Bala's to be weaker, but faster versions of the cero because they took too much time to generate and were must quicker. Therefore, the higher you are in this field, the more powerful, precise and quicker your cero's or bala's become. Along with that, those with higher skills in Cero can charge their blasts faster and begin to learn varying custom Cero's. (I.E. learning how to make an ice based cero or fire based cero; one of the most common variants.)

Regeneration: This is the ability that allows a Hollow to heal most injuries very quickly, with the exception of the destruction of the head or vital organs. With that said, the higher your level is with regeneration, the more quickly and efficiently your hollow will heal. Eventually, if you reach a high enough level, you will discover new ways to enhance this such as regeneration limbs, some fatal blows and things of this nature.
