The Eclipse Bros.

The Eclipse Brothers are two celestial beings who are brothers who are polar opposites of each other. There's Sol, the optimistic younger brother who personifies the sun, and Mani, the laid-back older brother who personifies the moon. Sol is fire, and Mani is ice. Sol is bright, and Mani is dark. Sol is hot, and Mani is cold. Despite their opposites, they both love each other dearly.
