The Candy Man see the homeless man spasm terribly on the ground, screaming in agony. Something would start to poke through his mouth from the inside of him. A Spider like appendage would begin to rip out from his body. Blood would gushed from his mouth as he continued to scream in utter pain before another spider leg thrust itself out of his mouth, silencing him. His torn body then bloated to twice his size, then burst in a shower of blood, revealing the black body of a new born horror. The new born creature would look around seemingly unaware of the Candyman at first before looking it's many eyes on him, then letting out a shriek. This shriek could be heard several blocks away it was so loud.
If he tries to cut it down, unless he kills it in one hit it will shriek anyway, but louder to ware it could heard throughout the city.
The Pyromaniac in time square will find his position picking up a lot of blips in all directions heading his way. The time square sign would suddenly burst off its mount and fall towards him as an lesser horror bursts from the building. It makes it's way towards the Pyromaniac on the ground. Several dozen other Horrors would burst from the building around the area taking down concrete and glass with them.
The Aeromancer would see some of the horrors floating towards him, but not as many as The Pyromaniac.
The Hydromancer, Big Tex, and Big Rodeo will encounter lots of movement in the steam, and find themselves being randomly attacked by leaches flying through the air. Random figures in the buildings would be seen moving around, five minutes into the random leach attacks gun fire would start sounding as the same figures take pot shots at them.
Again if you aren't mentioned nothing happened.
