The Big Bro is an enemy in Mother 3. They appear in Osohe Castle during Chapter 2. Its appearance is that of a pink creature, with an old-looking face and lanky arms and legs. Despite its name, the Big Bro is smaller than its relative, the Li'l Big Bro. They form a Bro Team later in the game, replacing all instances of the Big Bro in Osohe Castle.
