Bat Bots

The Bat Bots are four bat-based robots that first appeared in the season 2 episode, "Hallo-ZIM". They are also the archenemies of Master Yu, a popular TV show that Zim likes to watch.

Characters
An evil group of bat-based robots, the Bat Bots, are programed to destroy planet Lovelandia. There are four Bat Bots in total, and each has its own color: Red, Yellow, Pink and Green. A doomsday device called the Batonator is created when all of the four Bat Bots combine themselves together. When Zim, Tak, Skoodge and Tenn were transformed, the four Bat Bots sought out each other and when they were united, they form the Batonator. After four minutes, the Batonator transformed into its "doomsday device" form, and started counting down from 59 seconds. Just before the timer ran out, the Real Potion wore off, and the Batonator turned back to Zim and the other Irken Invaders, who fell together into a harmless pile.

Description
Each on of the four Bat Bots are in the same shape, with red eyes, and vampire fangs. The only difference they have is their own main color of their respective bodies as well as the weapons they use. The Yellow Bat Bot has a blood bazooka in its mouth which he uses to turn anyone into vampires. Also, the Red Bat Bot has ice guns equipped in its shoulders that it used to shoot ice, and the Pink Bat Bot can freeze lasers from its eyes. The Bat Bots are created by the Real Potion spoke with the voices of Zim and the other three Irken Invaders (e.g. The Pink Bat Bot spoke with Tak's voice).

Trivia

 * When Zim and the other Irken Invaders transformed into real Bat Bots is very similar to the Jack-O-Bots from The Fairly OddParents episode, "Scary Godparents", as which the popular kids are turned into real Jack-O-Bots by Timmy's wish for everything to be real and scary on Halloween.
