K1 (The Autobots)

K1 (also known as K-1 with a hyphen/dash (-) symbol), is the main protagonist of the 2015 Chinese mockbuster film The Autobots.

Why He Sucks
NOTE: As further mentioned, most of these problems and/or issues were carried over from the latter three and the rest of the other characters.
 * 1) Like with K2 (K-2) and K3 (K-3), the producers didn't even bother to change his character design much, as his design is obviously very (extremely) similar to Lightning McQueen, so he is still identifiable. Except he actually looks more like a male non-Brazillian version of Carla Veloso, a racer from the said country, and which the film Autobots tries to rip-off specifically.
 * 2) *In addition, on the poster, not to mention that his expression is basically the same exact identical as McQueen on the poster of the actual Cars 2.
 * 3) **The second poster of the film also even has a mirror imaged (or inverted sideways) version of McQueen's artwork from the first Cars film. Even the "Lightyear" tire text was still present.
 * 4) Much like LITERALLY every other character in the film, he has the following problems:
 * 5) *Completely unrealistic car physics and stupid tire models.
 * 6) *His movements are very strange, as random parts of his body stretch and shrink.
 * 7) *His personalities are practically unidentifiable.
 * 8) *There's also little-to-no lip-syncing.
 * 9) *Lazy voice actor that can be barely understood, even by Chinese-speaking people. The audio quality is inconsistent; it sounds like the actor recorded on a different microphone.
 * 10) Just like with all of the other characters, his design is so bad to look at. In the poster, it STILL looks as good as the entire poster does! And it's better than in the actual film!

The Only Redeeming Quality

 * 1) Just like with most characters in the film (especially from the said quartet of the other two), his stretching and shrinking can be funny sometimes.

Trivia

 * Fun fact: He was the second Cars-based mockbuster character to be painted red. The first other being Sparky from the Car's Life series.
 * Coincidentally, even more interestingly enough, they are both the main protagonists of the two same films. Also, if you count the inspirations of Cars for other media, these include; Roary the Racing Car from the show of the same name, and Blaze from Blaze and the Monster Machines.
 * If not affective by the film's quality, he actually resembles more of a male non-Brazillian version of Carla Veloso, a racer from the said country in Cars 2.
