• Manfred "Manny" (The Mammoth): Voiced by Chikao Ohtsuka in the early films (and later by other veterans in sequels). Ohtsuka was a legendary figure in the Japanese voice acting industry, known for roles like Gol D. Roger in One Piece and Goemon in Lupin III. His voice provided a gruff, fatherly gravitas that grounded Manny’s cynical yet gentle personality.
• Sid (The Sloth): Voiced by Kappei Yamaguchi. This was a crucial casting choice. Yamaguchi is famous for high-energy, slightly chaotic characters like Usopp in One Piece and Ranma Saotome in Ranma ½. His portrayal of Sid amped up the character's annoying yet endearing qualities, using a higher pitch and faster delivery to match John Leguizamo's iconic slur.
• Diego (The Saber-toothed Tiger): Voiced by Tesshō Genda (in the first film). Genda is another titan of the industry, known for voicing tough, masculine characters like Kurama in Naruto and the Japanese dub voice for Arnold Schwarzenegger. His deep, resonant voice perfectly captured Diego’s transition from villainous predator to loyal protector.

• Why it matters: Kōji Yakusho is a heavyweight in Japanese cinema, famous for starring in Shall We Dance? and, more recently, winning Best Actor at the Cannes Film Festival for Perfect Days.
