Widget was originally nothing more than a round floating head. After Burt realigned Widget's circuitry in Excalibur (1st series) #42 he began attempting to grow a body, which culminated in his current state of multi-dimensional phase. Shortly thereafter, Widget began to spontaneously appear to the members of Excalibur in an attempt to warn them. #66-67 revealed that the spirit of Kate Pryde from the Days of Future Past had taken up residence in Widget. It is unclear what intelligence drove Widget when he/she/it(?) was allied with Kang.
