Chromaggus, Nefarian's Hound

If another Beast you control would deal damage,
it deals twice that much damage instead.
{r}: Chromaggus deals 1 damage to each creature.
{b}{b}{r}{r}: Chromaggus deals 2 damage to each creature and player.
It is speculated that he was created by Nefarian experimenting on captured Core Hounds.
