Violet clapped her hands twice and the simulation started. We were then standing in the sky, looking down on the area.
We all saw a dark, giant, gaping hole in the ground. A dimension breach the size of a stadium. Creatures made out of dark purple slime were coming out of it.
I saw as they changed forms and resisted damage from many heroes. Only overwhelming power or unique abilities could take them down for good. As cutting them in two only multiplied them.
"Wow, I see why this was really bad. The slime invaders are shapeshifters. They can mimic powers and magics to a degree as well. Their bodies were resilient to anything that didn't atomize them or was unique.", I analyzed.
