As the Water Sentinel began to advance toward them, Mako quickly explained that they had to defeat the water monster quickly if they ever hoped to win and that their water ability was useless against it.
The Water Sentinel was 12 feet tall and was completely made out of water, some of the water had coagulated to become solid, yet it didn't resemble ice. It had two glowing teal-colored eyes and a giant mouth with teeth made out of that solid water.
Mako knew they had to act fast to defeat the Water Sentinel before Team B arrived. Countless thoughts of strategies ran through Mako's mind as he tried to utilize his team's combination of abilities to their advantage.
Since Water had no effect on the thing, he would try the only logical ability to counter its nature, Fire!
Mako, Iris, and Erin dodged the sentinel's giant water jet attack by rolling across the floor in the nick of time.
