Ankylometrodon

"The Ankylometrodon is not just a powerful weapon, it can also survive the fiercest enemy. The base creature is a mixture of Ankylosaurs, for the tail and armor, and Dimetrodon, for speed and predatory nature. I strengthened  the armor by adding the genome of Doedicurus giving it tail spikes as well. The creature’s armor might be functional against today’s monsters, but what about those of tomorrow? I combined this creature with the Turritopsis nutricula  regenerating Jellyfish. You may have noticed that this creature seems to fight with electric blasts as well as tooth and claw. During a field test the creature demolished the electric fencing surrounding a target, because of its regeneration it fused with the material. I also spliced in the genome of a bacteria intended for bio-warfare which proved to be resistant to nuclear charges. Suffice it to say this creature should withstand even the most severe of modern technology." Dr. J. Smith
