History
Emma Frost removed the mental blocks that prevented David Alleyne from retaining the knowledge he absorbs. Thanks to it David quickly surpassed all the teachers at the institute, having permanently retained all the knowledge they possessed, and then left the institute.[2]
Eighteen years later, David became the President of the United States and planned to establish world peace. In order to do so, he decided to teleport nuclear weapons directly to China to completely destroy it in one attack. Noriko Ashida learned about his plans and informed Danielle Moonstar about it, hoping what she and the X-Men would be able to stop David. The plan, however, failed, David killed Dani and the X-Men.[1]
