@Kuma_From_Argentina: Luckily but uncomfortable for Alvin, the shock of the water knocked him back up to the ropes, the fish flying into the audience. A small pang of guilt was felt, but Alvin was surprisingly okay with that.
He felt around the worlds he had created, searching for something he could use as a weapon before Gen launched one of those skull crunching punches of his- YES.
Opening a portal right in front of him and another on the planet CircleParty3000, he intercepted a Friartuckasaurus mid-charge. While he had unlimited creative powers on the other side of the portals, raising mountains and carving out oceans merely by willing it to be so, here on Earth Alvin was merely agile and sturdy, so he would have to throw his punches from where he could get the strength.
In this situation, this strong punch took the form of a rampaging dinosaur with a nine-inch thick skull. Of course, Alvin wasn't just going to bring in a stegosaurus or something stupid. That'd probably kill Alvin too. Of course, speedy thing go in, speedy thing comes out, and the dinosaur, which Hagane would recognise as a Pachycephalosaurus, had its head down and didn't notice it's rival was replaced with a teenage Japanese boxer.
That wasn't Alvin's problem. He'd probably just get rid of it with another portal afterwards.
