A sad loss, a pokemon fan fiction

One day, i was walking through the city with my marill by my side. I didnt see a giant storm coming until marill alerted me. "Marill! Marill! Mar mar!" It said. "What is it, marill?" I said. It pointed behind me. I saw clouds as dark, if not darker than, nightshade. The storm was coming as fast as deoxys using extreme speed. "That storm is coming quick!" I said. All of a sudden, it started pouring. It got as dark as night. We ran to find shelter, and the sky turned brown. "Its a tornado!" I said. All of a sudden, a funnel cloud dropped down to the ground. The tornado was coming right toward us. We decided to head down to the gym in the city. It was underground, so it was perfect. When we entered, an onix as big as a wailord came out of the ground and went right back in. "Well, that was onixpected!" I said. As soon as the tornado lifted, we left the gym and head back out. The storm was still barreling through. The rain was so heavy, there was a flood. Marril was swept into the flood. "marril!" I called out. "marill marill!" It called out. All of a sudden, lightning struck the water with marill in it! "Marrrrrrilllllll!" It screamed, as it got shocked. The flood died down and it was still raining. I ran over to marill and picked it up. It took its last breath as i held it. "Mar-ill" it said as it gasped for air. It died in my arms. "Marill, no!" I said. I started crying. I found a place to bury it. When i found the perfect spot, i did. "Goodbye, marill." I said. I broke down on the spot and cried my eyes out.
