Garfield has many alter egos in the comic strips and occasionally in other media.
The Caped AvengerThis is Garfield's most used alter ego. In this alter ego, Garfield usually wears his blanket or towel around his neck as a cape, hence the name. While he is the caped Avenger, Garfield acts like a stereotypical superhero, always looking for people in need or villains to fight. Since Garfield's normally uneventful life provides neither of the two, Garfield resorts to making up situations or villains to satisfy his heroic fantasies. This usually backfires on Garfield as he tends to accidentally destroy things, or pick fights with opponents much stronger than him, like large dogs.
On one occasion, Garfield, as the Caped Avenger, tried to 'save' a cheeseburger Jon was eating, proclaiming Jon to be 'the infamous Dr. Dweeb'. As a result, Jon ties him up in his cape, abruptly ending Garfield's heroic fantasy.
Occasionally, Odie will become his sidekick, taking the name "Slurp". Garfield also occasionally uses the Caped Avenger alter ego in the animated shows.
Garfield pulls out a claw and uses it to try to fight. The jig is soon up, however, after tangling with The Fang.
Garfield puts his blanket on himself and walks around, pretending to be an amoeba.
Garfield puts a banana peel on his head and carries bananas around. His mission is to entertain folks. When Jon is fed up with the act, Garfield decides to become Chicken Man (who has a rubber chicken hat and holds two chickens).
Garfield twice put on a green cape and called himself "Super Garfield and his sidekick Odie boy" he first did this in 2007 and the second time from 11 January 2010 to the 16 January 2010
