OK.

Steven Strange never had the 616 accident that took away his hands, but he retired from surgery. Thus, he had little to do, and soon studied up on sorcery. Reading all books, and mastering all spells, he soon took the notice of Eternity, declaring him Sorcerer Supreme, which he took as a codename. He also takes the notice of Mar-Vell, and after scuffling with him accidentally, assembles the Defenders.

Rogue is a character with little certain backstory. It's known that anyone she kills touches her, and she used this power to become an esteemed mercenary. But she soon tired of this, and wanted to make up for her wrongs, so she tried to join the X-Men to get close to Gambit, but was sent to X-Force instead due to her history.

Thor is similar to her 616 counterpart. Her illusion creation activates early, alienating her from her community. She then flees to an as-of-yet undetermined land, where she discovers Mjolnir and becomes the new Thor. She then designs an alternate "Moonstar" persona, and answers Strange's call to join the Defenders.

As for Sabretooth, little is known of him, except for the fact that he is very feral, and became a cannibalistic psychopath in Canada. He is soon found by X-Force. He has to be held captive by Magik's, well, magic, Deadpool calls him "Primal," and what captivates the X-Men, is that the only word he can say is "Wolverine."
