Evertt Thomas was an aquaintence of Jubilee's who died in one of the North American cullings. If his powers had manifested, he wold be possesses an aura which would allow him to be in synch with other super humans in his immediate vicinity, thereby gaining any powers they might possess. The powers Everett synched would fade some time after the superhuman he was in synch with left his vicinity, though with practice, he could have been able to retain those powers he acquired permanently. He would have also been able to track other mutants by allowing his aura to lock on to the mutant's bio-signature, with the aura naturally extending in the general direction of the mutant.
