It has been revealed that Colossus is dependent on the mutant enhancement drug Banshee for his super-human strength; without it, he cannot so much as lift his arms in his organic steel mode. It was also revealed that Peter came to work for the Russian mob after being banished from his home by his father, who had accidentally discovered him in bed with another man. Colossus briefly formed a Banshee-enhanced splinter group of X-Men, but they have since rejoined the main group drug-free.
