Alexa Vega goes from Spy Kid to Killjoy in her latest picture, Machete Kills.  The sequel, directed by Robert Rodriguez, features the return of the titular ex-Federale (Danny Trejo) as he attempts to stop a gang of arms-dealing terrorists.  Vega's character, Killjoy, is a hitwoman she describes as "a bodyguard of a whorehoues."  Vega recently talked at length about her character and embracing her sexuality.  We got our first glimpse of Vega in this black-and-white image from the picture that proved the starlet had grown up.  Now, we have a new full-color image of Vega as Killjoy that's even more revealing.

Machete Kills, also starring Michelle Rodriguez, Sofia Vergara, Amber Heard, Charlie Sheen, Lady Gaga, Antonio Banderas, Jessica Alba, Demian Bichir, Vanessa Hudgens, Cuba Gooding, Jr., William Sadler, Marko Zaror and Mel Gibson, opens next year.  Hit the jump to check out Vega's new look.

Here's the new image of Vega from Machete Kills, courtesy of Rolling Stone and Vega's own Twitter account.  If you look closely, you'll notice that some cars appear to be on fire or something in the background but who really cares about that:
