Dread Blattas are Mission Exclusive Enemies in Xenoblade Chronicles X. They are members of the Blatta family, and are fought at level 39 in the East Gate Plain of Primordia during route A of An Ancient Legend. Fifteen of them spawn initially, and they respawn approximately one minute after being killed. The party must defend against the onslaught for two minutes.
Dread Blattas do not drop any materials.
