The Tallests are Irk's leaders. They're the tallest Irkens on the planet (hence the name "Tallest"). Usually only one Irken is the Tallest, but these two are the exact same height, so they're both Irk's rulers. Their names are Purple and Red, Purple being the purple one and Red being the red one... no duh -_- The red one loves lasers, and seems to be the aggressive one. The purple one likes smoke machines better, and seems to be more intellegent. They're kind of jerks, and they were very rude to Zim when he came back to Irk, just because he was short. They don't have much respect for short Irkens. To directly quote one of them when they were looking at Invader Scrooge (can't remember who said it): "This is pathetic." But even if they are a little rude, we all know we love them =)
