Wonder Man
Can Rockslide learn to become rocks that hold significant erosion and historical value and self assess and learn all the secrets of history?
With that ability would he be able to surpass the Recorder in his job.
Being armed with accurate history the X-men would be better prepared to face their foes than ever before.
