Tony The Tiger is a former major character in the SuperMarioLogan series. He usually acts immature and a bit dimwitted for no apparent reason. He is the prototype of Jeffy.
Tony was adopted by Mario and Peach. Tony the Tiger made his first appearance in one of SuperMarioLogan's earliest videos and has been a recurring character ever since (in recent times, not as much). Tony first appeared in "Mario interviews: Tony the Tiger"; a video from SML released on December 30, 2007. He made his first appearance as the Frosted Flakes cereal mascot; Tony the Tiger.
He is portayed as obnoxious, rude, confused, always so happy, excited, and many believe he is may be retarded, despite a lack of confirmation by Logan. He is voiced by Logan's older brother Lance. Tony usually interrupts Mario's videos on YouTube and is an annoyance to Mario. Tony the Tiger was the first main SuperMarioLogan character besides Mario.
From his first appearance until around mid-2008, Tony was arguably the unstated main character of SuperMarioLogan. He was also Mario's sidekick for three years. In mid-2008; Mario and Luigi's stupid and dumb adventures was born and at that point Mario, Mama Luigi, and Bowser became the most popular SML characters.
When Mama Luigi died in 2009, it is inferred that Tony the Tiger returns to SuperMarioLogan as one of the main characters. Although, he still didn't appear that much. Only two other old SML characters have stood the tests of time; Shrek and Woody.
Shrek and Woody have become much more popular than Tony, as he hasn't had any videos recently and his future doesn't seem bright. He is now only used occasionally and rarely, but still lives with Mario.
