Hydria was resting in an underground cavern. The battle he had went through with the Godzilla knock-off and his female counterpart had tooken its toll on him. Eria or Aria was dealt with,but his hatred for the godzillasaur speacies remained strong. Though Zilla wasn't a Godzillasaur he was close enough to the real thing. Hydria thought that Zilla and any relatives of him would be easy kills if he ever ran into one,but he decieded a slow and alone life would make his life easier. Though it got boring at times it was better then another fight. The hyeana kaiju made his life go on by eating these giant insects he found abundent. He hated them. The tough, dry, then liquidy bug would make his spine and tail shiver when he ate one.
Hydria had spent many a years residing in those caverns. He even got comfortable with eating the bugs. But one day, the ceiling above him crashed as a bunch of mud and small metal creatures filled his home. He got pinned for awhile by the sudden implosion of the caverens and just laid there silently. He didn't like the feeling of being suppresed and didn't want to stay like this long, so he rose up as much as he could. Causing the walls around the initial crater to fall and sending oddly haired apes running and shouting. He saw the ape's odd contrapsions and put two and two together. These creatures had destroyed his resting place. With a new rage in his eyes he unleashed his high pitched beam attack on the machines. Causing the apes internal pain,slowly killing them all and destroying their machines in the progress. Leting out its signeture wail, Hydria made its way to the nearest ape settlement. Osaka.
