Disaster Demon

An in-named Demon. Once every 50 years will come to Earth and possess a mortal (usually a pilot, copilot or airline staff member), get on a plane (normally one possessing passengers numbering in the hundreds), and cause it to crash, killing all on board. If any member survives, he will repeat this process until all members of the first flight are killed. Any extra innocents killed are bonus points to him. He is a standard Low-level Demon with all the abilities and powers of such. As a Low-level Demon, he has all the weaknesses of one as well.
