Lashing out with tail and claws, he was advancing steadily through the ranks of defenders.  The occasional strike from a strong hero or one of the ranged combatants slowed him, made him stumble, if it hit in the right spot or pushed him off balance.

Stumble, but not much more, huh?

I hesitated to get closer.  I hated myself for doing it.  I was here for a reason, to do something.

And you found something to do, but damn it’s a scary something.

Legend fired a salvo of lasers at Leviathan, and the beams turned at right angles to strike Leviathan in precise areas, knocking his feet from under him, slamming him down into the road, catching him under the chin.

Shooting lasers around corners is such a silly idea for a superpower. It’s also awesome and I love it.

Leviathan raised a hand, and a geyser of water rose to block more incoming lasers.

Hm… fair enough. The transparency of water will only get you so far.

Legend’s lasers simply turned at angles to circle around Leviathan, strike the Endbringer from behind.  They left Leviathan so hot that his flesh glowed a yellow-orange around the areas they struck him.

Ooh! That’s the closest I’ve seen to Leviathan actually getting wounded so far.

As tough or invincible as a given cape might be, most were still hemmed in by the restrictions and boundaries of physics.

Arguable, but go on.

Getting hit by something that weighed nearly nine tons sent men, women, boys and girls in costume flying, if it didn’t kill them outright.

Oof.

Leviathan’s echo added surprising quantities of water to the battlefield.  Every step and movement he made, he filled the space he’d just left with water.

I don’t find it all that surprising. There are three main factors to how much water he leaves behind: how he moves, how fast he moves, and how big he is. As a huge and quick being, he’s gonna leave behind a lot of the stuff.

How much water did it take to displace something as big as he was?  However much it was, he created something like three times that amount when he took a single step forward, when you accounted for the space his body moved through.

And given how quickly he can take steps forward…

A hard amount to eyeball, because it had the same momentum his movements had, and some of it crossed great distances as he lunged and clawed his way through the front line of capes.

This is kind of odd, though. If he creates water behind his movement and it moves as quickly as he does or faster in the same direction, won’t a lot of the water just hit him in the back? That said, I get how claws can get out of the way by swinging, leaving the water to act like he’s throwing it.
