Smiley

Smiley was a Mobian Chipmunk and a Lieutenant in the Acorn Kingdom Army, serving as head of the Royal Secret Service following the death of his immediate superior and old comrade; Ian St. John. Smiley was close to Ian's only son; Geoffrey St. John, and became the father-figure and mentor to him that he now lacked.

Smiley served well during his time as head of the Secret Service, but later joined the Royal Underground following Doctor Robotnik's coup to fight to restore the realm.

After Robotnik's death at the hands of Sonic the Hedgehog, Smiley and the rest of the Underground joined up with the the Knothole Freedom Fighters to restore the decrepit capitol; Mobotropolis.

During a routine sweep-and-clear mission to destroy booby traps laid by Robotnik before his demise, Smiley accidenltly tripped a landmine that nearly got himself and Geoffrey killed, but while they both lived, Smiley, injured, realized that he was "too old for this game" and retired from active service; letting Geoffrey became leader of the reformed Secret Service.
