Terrence (Foster's Home for Imaginary Friends)

Terrence is a recurring antagonist in Foster's Home For Imaginary Friends and is arguably the series' main antagonist. He is Mac's older brother and greatest tormentor. He was voiced by Tara Strong.

Why He Sucks

 * 1) All he ever does is abuse Mac the entire time whenever their mother is out at work, which is an example of an abusive older brother, and he appears to be the worst bully out of all bullies in cartoons.
 * 2) In the beginning of "House of Bloo's", he beats up Mac and Bloo while using them as weapons to wreck the apartment, which was incredibly violent and abusive, and such actions could land him in jail or juvenile detention for that. Not to mention that he also got Mac blamed by their mother, who was also a jerk in the said episode, and if you look closely at Terrence's evil grin after hearing Mac's mother forcing Mac to get rid of Bloo, he got away with his violent behavior scot-free.
 * 3) He never got punished for abusing Mac and Bloo, or for wrecking the apartment in the first place, which might've sent a really bad moral to children saying it's okay for bully brothers to pick on their younger siblings.
 * 4) He often teams up with Duchess, who was another unlikable villain, and neither him or her got arrested for trying to kill Bloo with the Extremeasaurus.
 * 5) He locked Mac up in his own bedroom closet, which was also abusive of him to do that
 * 6) He was at his absolute worst in "Seeing Red" as he bullies Mac once again after "House of Bloo's", which tells that Mac's mother forcing Mac to get rid of Bloo didn't stop Terrence from abusing Mac, and not to mention that he also bullied Mac throughout the entire episode, which was unacceptable, because Mac didn't deserve to be tortured constantly.
 * 7) He was also unlikable in other episodes such as "Duchess of Wails" for example, which in that one, he teases Mac about going to Singapore after their mother threatened to move out, which horrifies Mac.
 * 8) In "Infernal Slumber", he threatens to tell his mother on Mac, and if Terrence's plan to get Mac and his friends from Foster's in trouble was successful, then their mother would've forbidden Mac from going to Foster's ever again, which would've made her even more unlikable.
 * 9) In "I Only Have Surprise For You", he humiliates his own little brother, Mac on his past birthdays and laughs at his misfortunes, and he never got punished for taking part of Mac's humiliation.
 * 10) He was also unlikable in the series finale, "Goodbye to Bloo", which he drops Mac's stuff onto the floor and breaks it, which makes Mac angry.
 * 11) He never got arrested for his violent actions towards Mac for years.

Redeeming Qualities

 * 1) He does get some comeuppance at the end of "House of Bloo's", when he was cornered by a Pegasus herd, and he also got his comeuppance in "Seeing Red" after Red threw him away in the dangerous traps Red himself went through with Bloo.
 * 2) He did have some funny lines, such as "...cause I know how stupid I...", which almost got Mac and Bloo laughing so hard.
 * 3) In "Berry Scary", that was the only time he was ever likable as it shows him changing the TV channels.
 * 4) In the credits sequence of the episode, "Infernal Slumber", he gets grounded by his mother.

Trivia

 * Tara Strong once said in an interview with voice actor Rob Paulsen that Terrence is her least favorite role she's done because it strained her vocal chords.
