And Logan was enraged enough that Nik's desperate move actually caught him by surprise. However, like his namesake the wolverine, no sooner had Logan's back smashed against a tree, that he was bouncing up on all fours and pouncing at Nik again. He did his best to steer clear of that vicious mouth full of sharp teeth while he pummeled at the man, not watching where the blows were landing aside from keeping them outside the realm of killing blows. His breathing was shaky, and he almost twitched from the effort of staying in control. Logan wasn't proud of what he was doing, but the father in him needed to send a message that nobody hurt his boy and went without some sort of retaliation.
"He ain't a saint, and he sure is an obnoxious asshole, but he's my boy. I ain't taking kindly to anyone hurtin' him," he even managed to growl at the much larger feral between blows, any bites and scratches he might be getting healing almost instantly. He aimed to slam the heel of his fist against Nik's nose, careful to pull his punch after factoring in his adamantium skeleton. He couldn't truly let go, not even for a moment, but his fangs were still bared as he fought, the image of Karr's scarred neck, hurriedly healed, clear in his mind's eye.
