Massimo Marone made his first appearance on "The Bold and the Beautiful" in the summer of 2001 when he was revealed to be a college flame of Stephanie Douglas, who was dating Eric Forrester at the time. Stephanie and Eric eventually get married but when Massimo returns to the fold, it's revealed that he and Stephanie have been keeping in touch behind Eric's back. Massimo gets involved with the couple's relationship drama when he offers to help Stephanie keep Eric's ex-wife, Brooke Logan, away from her son, Ridge Forrester.
After Ridge learns what Mossimo has done he's furious. However, the two are thrust together by fate when a medical emergency leads to blood work that reveals Ridge is the biological son of Massimo and not Eric. Massimo sees an opportunity to bond with his son and mentor him into taking over his business, Marrone Industries. However, he's devious in his ways and pits Ridge and his half-brother, Rick Forrester, against one another.
Eventually, Ridge begins working for his father and Massimo even makes him the sole heir to his business. Massimo and Ridge build their relationship, but things quickly change when Massimo finds out he has another long-lost son.
