Ukala

The Ukala is a powerful Aqua-Iravian object that gives the user immense strength and power when in a dire situation.

Appearance
The Ukala itself appears as a glowing blue orb, with smaller orbs radiating off of it.

Pre-Downpour
Incredibly little is known about the origins of the Ukala and whether or not it was used before the Downpour battle.

Hydro-Girl mentions that her people, Aqua-Iravians, gave it its name and that its use could also be dangerous.

Hydro-Girl vs. Vortak
During Vortak's attack on Downpour City, both Hydro-Girl and Kevin arrived to the area and looked on in horror at the devastation. As Kevin wondered what was to be done, Hydro-Girl gave him a restrained smile and kneeled down to the boy.

Hydro-Girl tells Kevin that she must sacrifice herself in order to stop the giant demon, causing a saddened Kevin to shed a tear which was then caught in the palm of Hydro-Girl's hand.

Placing his hand on Hydro-Girl's palm at her request, both their hands began forming a bright light which materialised into a powerful item. Knowing there was no other way to win this fight, Kevin wished Hydro-Girl luck and she gave a warm smile in return.

Walking through the ruined Downpour City, Hydro-Girl leapt onto a rooftop to confront Vortak who mocked her. Taking the Ukala, Hydro-Girl pushed it into her stomach and was then smacked away by Vortak. Landing in a river nearby, the river began to swirl violently until a now giant Hydro-Girl rose from the water.

In her new giant form, Hydro-Girl stared Vortak down in preparation for the battle of Downpour.
