Atlantica, homeland of King Triton.

Atlantica is the merfolk kingdom, located beneath the Atlantic Ocean, first appearing in the Disney franchise, The Little Mermaid. Ruled by the righteous and benevolent King Triton, Atlantica has been occasionaly saved by King Triton's subjects including his daughter, Ariel, and his advisor, Sebastian, from evil forces like Ursula, Morgana, the Evil Manta, and the Sharkanians.

Atlantica also appears in the villains tournaments, usually featured as one of Ursula's base of operations after Triton's defeat by various means. However, its presence in the Disney Heroes vs. Villains War is reminiscent to the original franchise, with the villains temporary ruling the kingdom before its restoration by Triton and Ariel.
