There are no secret tricks to work around it unless you have Black widow duped or cross bones, but even than you're still gonna need to play pretty well.
Just be patient and keep alert. Don't attack when he dodges back and charges and when he does charge you swipe back because it may be unblockable. If you can't take him or with a single champ don't move on past him unless you wanna spend a lot of units.
I found that wolverine works well with his regen as he can regen blocked hits or even fix small slip ups, it is still a long battle. Also Yellow Jacket did well because his power sting by passes the safe guard.
