First Appearance: X-Men #1 (1963)
Biography by Iceman
When the X-Men were captured by the living Island Krakoa, and were saved by the new assembled X-Men, or how Iceman would call them - "Old X-Men", or "Inexperienced X-Men", he and the other 3 original X-Men left the team ( Cyclops stayed ). After leaving the team, he graduated his studies - but somehow he couldn't find a normal office job. So, when Warren (Angel), and Hank (Beast) founded the group - "The Defenders", he was the first to join it. The group didn't hold much time.
But exactly when Bobby thought his Heroic Days are over, Phoenix was found in the bottom of the Madison Bay by Mr. Fantastic, and the Five original X-Men were joined again only to found X-Factor. After X-Factor, in the lead of Cyclops, helped Xavier defeat the Shadow King, the members of X-Factor joined the X-Men once more, where Bobby is still is.
One of the importance events in Iceman's life was when Emma Frost,
The White Queen,
today Co-Leader of Generation X, recovered.
He asked her to help him to develop his powers but instead she took
control over his body.
She didn't just took control over his body, but even used his powers
better than him.
When GateWay kidnapped him, Cyclops,
Wolverine
and Storm
to a mysterious valley,
to test their capabilities.
When they woke up, everybody were suffering from injuries, but couldn't
recall what caused it.
Iceman was the one who was hurt the most - he had a hole right through
his chest.
He asked the White Queen to help him heal. At the end, you could say
she helped him.
Today he learns new ways to control his powers - example: When he and his fellow X-Men fought Onslaught, he knew Onslaught was messing up with their normal perception of things, so he was concentrated on seeing everything only in terms of body temperatures. He saw him as soon as he entered the room.
He helped fighting Bastion when Operation: Zero Tolerance started, and he had to leave his father after he was bit up by Creed's men for protesting against Creed. With the help of Dr. Reyes and Marrow he finally succeeded to survive the Operation, and even fight Bastion himself!!
