The slugs from Deathstroke's rifle punched into Fenrir's muscled chest, with enough force to knock the beast back a step or two. Not enough to kill him, but more than enough to enrage him even more. The wolfman was more determined than ever to tear the foolish intruder's face off, to shatter his bones and shred his flesh. The cowardly mercenary fled upwards towards the lighting fixtures and drew his sword, thinking he would be safe up there, or that perhaps Fenrir would fear the blade. The wolfman could smell the enchantment on the blade from here, the whiff of magic smelling to him like burning ozone. He had dealt with such weapons before, and yet here he stood. Deathstroke would have to try harder than that. 

The big metahuman readied himself to leap up to the rafters, it would be an easy task for him, when he heard the crashing that sounded like thunder. He swung his head to face the source of the noise. Boom, boom boom, BOOM! 

The wall bent inwards then exploded with brick and mortar flying at all angles, Patriot at the source of the disruption. The wolfman was momentarily stunned at his pack mates apparent stupidity. Did he not realise they were underground, with thousands, perhaps millions of tonnes of rock above them. Even with Fenrir's limited understanding of architecture he knew that the flying superhero could have seriously jeopardised the structural integrity of the base and endangered all their lives. Perhaps Patriot and Fenrir would survive the possible cataclysm, but not all their pack mates were as sturdy. The feral metahuman's powerful sense of hearing could already make out the faint cracking noises coming from Patriot's path of destruction. He figure it was only a matter of time until the base's roof collapsed, burying all of them under the unrelenting weight of rock and concrete. Panic began to grip the big metahuman. They had to finish up with Deathstroke quickly then get out, or else his entire pack would pay the price. 

"Patriot!" he began to roar, meaning to warn the superhuman of the threat, but was cut off by Superman's protégé firing a powerful blast of energy at Deathstroke. The nimble mercenary dodged the blast, flipping from one support to the other with the grace of an experienced acrobat. Patriot's energy exploded though, ripping through the steel of the light fixtures. The metal made a horrible screeching noise before giving way, falling towards the floor, Fenrir standing directly below. 

The wolfman managed one agitated growl before the remains of the fixture collapsed with a crash on top of him, burying Fenrir under a mound of twisted, half melted metal.
