The Meerca Brothers are a duo of thieves in the Neopets franchise. As you can tell from their group name, they are both Meercas. Their individual names are Hermeedjet and Merouladen. The two Meercas wear different outfits so that people can distinguish one of the brothers from the other. Even their thieving outfits are different to make the brothers distinguishable.
The Meerca Brothers have a trading card and on that card lies a note speaking of a master they serve. It is unknown who this master is.
