Brighton

Brighton is a character who appears like a sun, who gets into a fight with the moon, Twila, in the game Mario Party 6. He was the one who started the feud by asking Twila, "Who's more impressive? You or me?" He refers himself to be "cooler" than Twila. Brighton also controls the board for three turns and switches off with Twila after the three turns are up.

Once all pages in the Miracle Book are bought, Brighton and Twila see how much work everyone has done to fill the Star Bank. They both make up and promise to get along. As an award for their hard work, the sun and moon scatter the Stars across the sky, being seen miles away. Thusly, he ended his feud with Twila. He also hosts Mic Mode and Solo Mode and appears in Super Smash Bros. Brawl as a sticker.
