Tweety

Tweety (also known as Tweety Pie and Tweety Bird) is a yellow canary in the Looney Tunes and Merrie Melodies series.

Why He’s A Tweet Little Birdie

 * 1) His design, along with his voice, are both really cute.
 * 2) He has many memorable quotes such as "I tawt I taw a puddy tat!", "I did! I did taw a puddy tat!" and "Aw, the poor puddy tat! He fall down and go... BOOM!!"
 * 3) His rivalry with Sylvester Pussycat is very iconic and humorous.
 * 4) Much like The Road Runner and Jerry Mouse, his ways of resourcefully thwarting Sylvester's plans are very entertaining.
 * 5) Mel Blanc did a good job at voice acting him.
 * 6) * Other voice actors, such as Samuel Vincent, and Eric Bauza also do an excellent job voicing him.
 * 7) Just like Jerry Mouse and Bugs Bunny, he may seem incredibly lucky and flawless on the surface when it comes to his rivalry with Sylvester, but he has had his moments of showing how comically flawed or vulnerable he can be for viewers to find him likable or for viewers to find him interesting enough to be someone the audience can root for as well (especially Bob Clampett's version of Tweety).
 * 8) He even has 2 movies, Tweety’s High Flying Adventure and King Tweety
 * 9) He’s one of the biggest marketing icons for Looney Tunes.
 * 10) He sometimes cares about Sylvester.
 * 11) He is extremely big-hearted and is willing to help people whenever they need help, an example of this is "Tweet Team" where he along with his friends saves Speedy Gonzales' friends from a gang of cats.
 * 12) His singing is extremely heart melting and adorable.

Bad Qualities

 * 1) He is often misjudged for his gender, it's actually hard to tell if he is a boy or girl, however, Warner Bros has said Tweety is male.
 * 2) He is often cruel to Sylvester (especially in Looney Tunes Cartoons).
 * 3) Depending on your view, he was unlikeable in the New Looney Tunes episode, "Etiquette Shmetiquette".
 * 4) Much like Jerry Mouse or even Kevin MaCallister in Home Alone 2, He can have too much fun surviving and some of his traps against Sylvester (and other characters) can be over-the-top levels of cruelty and does show how painfully lucky they can be (especially Chuck Jones's iconic version of Tweety).
 * 5) *Speaking of "Bob Clampett's version", His early design in the first three shorts looked pretty uncanny as he got no feathers.
 * 6) He can be somewhat clueless at times, in an episode of The Sylvester & Tweety Mysteries, whenever Sylvester was being chased by a bull, he thought he was having fun even though it was painfully obvious he wasn’t, the same can be said for Granny and Hector.
 * 7) For fans, at times, he's considered to be an overrated Looney Tunes character.
 * 8) Since he is in the role of prey, unsurprisingly, he can sometimes be a little bit of a butt-monkey, and the fact that Sylvester can be very antipathetic to him doesn't make it any better.

Trivia
1. Although he doesn't show fear, some Looney Tunes fans speculate that Tweety secretly is terrified of Sylvester, the reason he doesn't show it is because his owner is there to protect him.
