As a Jaffa, Teal'c is a genetically modified human with an abdominal pouch that serves as an incubator for a larval Goa'uld.

Teal'c's most notable feature is a golden tattoo found on his forehead, a sign that he once served the System Lord Apophis as First Prime, the most senior Jaffa rank.

In 2002, Christopher Judge was nominated for a Saturn Award in the category "Best Supporting Actor in a Television Series".

In the hopes of avenging his father's death one day, Teal'c joined the armies of the rival System Lord Apophis.

His interaction with Bra'tac and his own personal experiences eventually led Teal'c to doubt the divinity of the Goa'uld.

[4] Teal'c finds a home at Stargate Command (SGC) on Earth and occasionally visits his wife Drey'auc and his young son Rya'c on Chulak (see section Relationships).

[5] Teal'c and Bra'tac lose their symbiotes after a sabotaged Rebel Jaffa summit in season 6's "The Changeling", but the Tok'ra drug Tretonin sustains them from then on.

No longer presenting a security risk to Earth, Teal'c attempts to have a normal life and moves out of the SGC in season 8's "Affinity".

The new Jaffa Nation immediately becomes a major power, inheriting part of the fleets of the System Lords.

In the series finale, "Unending", Teal'c spends fifty years frozen in time on the Odyssey with the rest of SG-1 when Carter triggers a time dilation device to prevent them being destroyed by an Ori battlecruiser, but when she finds a way to escape and save the Odyssey that requires one person to go back to the moment before time froze, Teal'c volunteers as his Jaffa nature meant that aging fifty years wouldn't be as significant to him as it would be to his human colleagues.

As a result, Teal'c is the only one who remembers what took place during the time dilation device, but he vowed to never share that information with others, and apart from having gained a white streak in his hair his physical potential remains relatively unaffected.

In "Midway", he comes to Atlantis at Carter's request to teach Satedan warrior Ronon Dex how to deal with IOA interviews.

When the Wraith leave the Pegasus galaxy and set foot at the SGC, Teal'c and Ronon work together to stop the enemy.

[7] As a Jaffa, Teal'c does not require sleep, but must engage in a form of meditation called kel'no'reem in order to synchronize with his symbiote.

He once stated a dislike for "bovine lactose",[12] which may be due to an earlier episode ("Unnatural Selection"), in which Teal'c is seen gorging himself on ice cream and even stealing O'Neill's pint of ice cream from his hand when the Asgard beamed the refrigerated stores onto the Prometheus, implying that Teal'c may be lactose intolerant.

In season 8, Judge wanted to take Teal'c one step closer to being more aware of Earth customs with a more Earth-like behavior, without him losing his alien perspective.

Teal'c rekindles his feelings with a Tuk'ac temple priestess named Shau'nac in season 4's "Crossroads", but she is murdered soon thereafter.

[18] Christopher Judge explained that his character's amusement with Vala in seasons 9 and 10 contributed to Teal'c's loosening up.

Rumors began to surface at the end of season 3 that Judge would leave the show, but they were quickly and firmly denied.

[9] Judge received his first story credit for the season 5 episode "The Warrior", and later wrote "The Changeling" on his own, focusing on Teal'c's self-identity.

[10] The producers' original idea for Teal'c included long ears and a specific beard piece, but the make-up department got it down to just a forehead symbol, an Egyptian look, and the character's gold skin tone.

[27] With the beginning of season 8, after "many years of begging, pleading and politicking", Judge approached the producers again and asked for his character to have hair, and they gave in.

Judge showed the cornrows hairstyle that he thought Teal'c would have, at a convention, but the hair was cut short before the shooting of season 8 began.
