Crap! There's no mention of the endings for Battle & Chase.
Anything you want me to add on?
Here's the B&C ending writeup. Either I plum forgot or it got deleted. Either way, wrote this fresh:
Besting Wily in a race earns an ending for the character chosen. Each ending showcases a unique way the winner celebrate or spends his or her hard-earned cash prize. They're simple-- sometimes rather benign-- little artwork stills, but some have a humorous tinge to them, like Spring Man buying too many weights for his body or Guts Man getting booed out for his painfullly sung enka tune on karaoke. There are a few interesting twists on characterizations; Ice Man is portrayed having a crush on Roll as he made an ice scuplture of her and him together in the South Pole, and Quick Man strives to challenge his rival: former champion Turbo Man (why wasn't HE in this game?). A flawless run as Roll grants the player a special added ending song for her: "Kaze yo Tsutaete" sung by Yoshino Aoki. "Kaze" would become Roll's theme song in various later games and spin-offs.
You can place the paragraph after "E-rated Carmaddegon" line. You can link to the song (posted by drpepperfan above) if you like.
