She thought it was ridiculous, but it was the only name he had. Only name he knew. The only thing he had tied to him. So regardless of her thoughts, he didn't care. He was who he was, simple as that. Now this pokemon though, it was going to have to learn who to respect the hard way.
With her further suggestion Starkiller waved off the idea. Everything wanted space, but didn't mean that was the case. Speaking to it again, he pointed at the pokemon. "Alright. Lets try that again, shall we?" And like on cue, the pokemon came rushing forward swinging. With the help of the Force, he deftly dodge each strike as it came forward. Then Starkiller countered and flat palmed the pokemon causing it to double back some. Then the exchanged happened again. Starkiller was careful on the force he used, and using any of his dark side Force abilities, like injure or kill. He wanted it alive, not mortally wounded.
After a moment, Starkiller just stopped and held his hand out causing the pokemon to freeze completely. Lucario obviously was confused by the action, especially when it was lifted off the ground. "I didn't want it to come to this." Starkiller expressed calmly.
