"How am I supposed to use my mutation without bringing it out?"
Lizzie turned into nothing but a blur as she attacked Atlan from the front. Atlan quickly put up his two arms as a guard on his entire torso, which successfully blocked her claws and only damaged his arms.
But Lizzie didn't take a second longer as she slipped past him and disappeared from his view.
Atlan turned around, but she followed his movements perfectly and stayed behind him, out of sight.
He faked turning around and waited a second for her to run in front of him, but it seemed that she was wise to his tricks too. She pounced on his head and gave him a little tap on his hair, just enough for him to feel a little bit disoriented.
Whichever way he went, she was always one step ahead of him. He couldn't get a grasp on where she was, therefore he was unable to completely dodge away from her attacks.
