Biography: Turning Point
The turning point in Bobby's attitude toward himself and his powers began with Uncanny X-Men #292, when Mikhail Rasputin used his powers to change Bobby from Iceman to a puddle of water, then to solid ice.
Mikhail offered Bobby a glimpse at the potential of his ice powers. And after that incident, Bobby began to question his approach toward the development of his powers -- and toward his life in general -- and began to experiment a bit. For example, in Uncanny X-Men #300, he creates a massive ice "log" to slam the Acolyte Frenzy through a wall.
Bobby's perceived "slackerness" truly didn't begin to bother him until after Uncanny X-Men #314, when Emma Frost (the White Queen) possessed his body.The "body swap" took place in Uncanny X-Men #311, when Bobby used his own body to protect the then-comatose Emma from a Shi'ar power surge in the MedLab. Emma's mind was somehow transferred to Bobby's body in the process, and when she regained consciousness in Uncanny X-Men #314, she escaped the mansion and returned to her business Frost Enterprises to learn the fate of her students, the Hellions. During this time, Emma used Bobby's powers in ways he'd never dreamed, from melting under doors and then reforming to "swimming" three miles down the Hudson River in five seconds by converting her body to water.
After the Phalanx Covenant crossover, Bobby confronted Emma (in Uncanny X-Men #318) about what she had been able to do with his powers.
Over the next several issues, Bobby alternately joked and angsted about his issues with self-confidence, and during this time grows closer to Rogue, who had personal issues of her own. The two began to talk in X-Men #38, and she accompanied him to dinner with his parents (and backed him in a confrontation with his bigoted father) in Uncanny X-Men #319.Bobby then began to take things more seriously after that, exploring his powers to some degree and just altogether calming down a bit. During the Onslaught debacle, for example, he adjusted his vision to see body temperatures when Onslaught had blocked out telepathic and visual perception of his approach. Later, he went undercover as Drake Roberts to work for Graydon Creed's presidential campaign, a task that required a level of sobriety and seriousness Bobby was normally not associated with.
