*Clears throat*
Beast, fairly easily.
Beast's most recent rating have put him at about 40 tons of lifting strength. Not 25, not 2, and certainly not 1. 40 tons. Beast has a slight form of healing, while it isn't as strong as Sabretooths, it is enough to help Beast out. Beast can leap out of a second story building and land on his feet with out so much as a stumble. From two stories up. Beast does have enhanced relexes and agility, while they are not in Spidey's level, they can rival him and are many times greater than Sabretooth's. Beast may not be as good in a hand-to-hand fight, but he is good enough to hold his own without his strength, healing, agility, speed, reflexes, and intelligence. With those, this shouldn't even be a fight. Sabretooth has a possibility of winning, but Beast wins 9 times out of 10...
