"Teen Titans" Super Post!

As we've seen, if a tv adaptation is popular, you can guarantee that it will have a strong impact on canon.  And as you'll see below, Teen Titans is no exception:

Red X

Red X first appeared as an undercover identity for Robin in the Teen Titans episode "Masks" (2003), and later, in the episode "X" (2004), somebody steals the costume and begins using the persona for himself.  In Terror Titans #2 (January 2009),  Red X is mentioned as a thief the team is looking for.

Teen Titans also affected the looks of several characters and introduced some other ideas as well:

Beast Boy

Cyborg 2.0

Hot Spot's name and look

Originally using the name Joto (Swahili for "heat"), he was called "Hot Spot" when he appeared on the Teen Titans cartoon - presumably because it's more easily associated with his powers (and, according to Rorshach_42 on the CBR forums, "Joto" is a slur in Spanish).  When he joined the Teen Titans during the One Year Gap (Teen Titans #34, April 2006), he also used the name.

Bumblebee

HIVE Academy

The HIVE Academy first appeared in the Teen Titans episode "Final Exam" (2003) as a training ground for supervillains.  In DC Special: Cyborg #6 (December 2008), Gizmo II was mentioned to have formerly been a student there.

Teen Titans' Hometown

Despite the Titans' usually being based out of New York City, the animated series (July 2003) put them in an unnamed city on the West Coast that felt a lot like San Francisco.  In Teen Titans #1 (September 2003), the team moved to San Francisco proper.
