Windshear (Alpha Flight)

Colin grew up mostly in Canada, but moved to England with his step-father and mother in his pre-teens. He discovered his mutant powers as a teenager when he was attacked. He subconsciously used his powers to make the gym bag he was carrying have the weight of a brick and used that to subdue his attackers. He would later serve with the Canadian Armed Forces before eventually coming to be a Roxxon super-powered employee.

Member of Alpha Flight

Ashamed of the villainous deeds he was forced to perform as a special operative for Roxxon Oil, Windshear quit and became an official member of Alpha Flight. He served as an administrator and adviser to Beta Flight. During his time with Alpha Flight, Windshear gradually became more comfortable with the role of a super hero.

When the Canadian government disbanded Alpha Flight, Windshear retired from the super hero life and returned to his home in England, where he set up a curio shop that sold high-priced objects, created with his mutant power, that were only visible under special lighting.

Hume was later revealed to be depowered.

Leukemia and Chinook
After being diagnosed with leukemia, Colin decided that being a sculptor wasn't for him anymore, he missed the life he lived as an adventurer and the feeling he got by helping people. Calling himself Chinook, Colin rescued X-23 after she got caught up in a gang fight at a club owned by the Pink Pearl in Toronto.

Taking her back to his place to recover, he explained to her why he still does it after everything he had been through. That the suit makes him a symbol, not just a man and the bright colors can't be stained by past mistakes and regrets. He reminded her of Logan, so X-23 decided to help Colin by taking out Pink Pearl at her hideout.
