Sneer

Rychard sneered. Even the unmodified Rain Beasts, at this size, were practically immune to Water Force. Let alone Water Force, because they could expel so much water at once, their defenses were nigh impenetrable. Punching them quite literally felt like punch a large ball of cotton, it wasn't just a look, it was a feature. 

There was a reason the Rain Galaxy didn't allow them to get this large. Although they were generally harmless, when they grew to a certain size they were almost undefeatable. The only real way to handle them was to take them away from a source of water and allow them to run out of water to use and manipulate, then they would become no less docile than any other domesticated creature. However, Leonel didn't even have this option. 

Just judging by the closing green pads, Leonel was obviously trying to protect this city. If he wasn't, he would be too foolish.
