"Open up a energy field that utilizes a mysterious power. Allies who come incontact with the field will be healed."
— Dragon Ball: Xenoverse in-game description
Energy Zone is a supportive healing technique where the user throws Towa's staff/spear into the ground (or air when not on the ground) and draws the Time Breaker symbol creating magic circle and uses rapid movement to teleport into the circle and grabs Towa's staff/spear while spinning around gracefully before launching a dark Energy Sphere upwards, which produces a circular zone of energy that heals the user and any allies in contact with the zone.
When the user is someone other than Towa herself, then they will simply draw the symbol and teleport into the zone while spinning around gracefully before launching a dark Energy Sphere upwards, which produces a circular zone of energy that heals the user and any allies in contact with the zone and do not use Towa's Spear Staff to case the spell at all indicating that the spear staff is not required to perform the technique.
Appearances in Games
Energy Zone was named and first appeared in Dragon Ball: Xenoverse as part of the GT Pack 2 DLC and is Towa's Ultimate Skill. It can also be obtained by the Future Warrior as a reward in DLC Parallel Quest Event: "Insidious Plot". It is one of the few Ultimate Skills that do not cause any damage. In Dragon Ball Heroes, Darkness Towa has an offensive version of this technique, called Minus Kiri Zone.
