Which breakfast-cereal mascot is the cartoon tiger named Tony?

The breakfast-cereal mascot named Tony is Tony the Tiger.

Tony the Tiger was created for Kellogg's Frosted Flakes, known as Frosties in some countries. He first appeared in 1952, joining a group of proposed cereal mascots that included a kangaroo, a gnu, and an elephant. Tony eventually became the lasting representative of the brand.

His best-known advertising phrase is “They’re gr-r-reat!”, which emphasizes the cereal’s sweet, frosted coating. The character’s design changed over time: early versions looked shorter and more animal-like, while later advertising presented Tony as a tall, athletic, friendly tiger.

Tony is sometimes confused with other cereal mascots, especially Toucan Sam, who represents Froot Loops, or Lucky the Leprechaun, who represents Lucky Charms. Tony’s association is specifically with Frosted Flakes and its international versions.
