Some highlights include fighting with Superboy, dodging rapid fire heat vision attacks from Mon El and throwing him into another solar system (Post crisis, too!), and clearing thousands of tons of snow with a single punch.
Why the big gap between the second and third Vals? The third one could still toss around Ultraboy no prob, shatter hundreds of feet of ice with a punch, break forcefields, etc..
Well, the second Val had better senses than even Pre-Crisis Val. He did hear Emerald Empress miles away by only her heartbeat. He also knows the other persons moves before they do it, like Batgirl. 3boot has done some good stuff, but doesn't have the feats. TBH, Gorgon can do anything 3boot can. So, it's not that impressive.
He's still able to dodge speedster level attacks. Thor'll have a hard time connecting.
Don't believe 3boot has the uber feats like breaking through inertron though.... But than, while Thor's durable, he's not known for his impenetrable skin either.
