Wildmutt's mutation is perhaps the most unique, and most horrifying, of the ten’s mutations. The mutation resulted in the merging of three Wildmutt’s pups while they were developing, giving birth to what can simply be described as an alien Cerberus. The fusion is (unsurprisingly) no perfect, with Wildmutt having to share his mind with those of his siblings, while each of their mouths fight against each other for sustenance, while the combined mass of their skeletal systems pierces its way through his skin. The constant pain and hunger drives Wildmutt into a constant frenzy, lashing out at anything he can find and tearing it apart with three insatiable maws.
