Brother, you? merciful? You're making me laugh
Lucifer jumped out of the ring of fire when he attacked, but he couldn't dodge the crunch, which left a mark on his shoulder. He flinched a little, but when he saw the Houndoom heading towards him with thunder fang, he jumped back, dodging the attack. Before Lucifer could react, the Houndoom released Sacred Fire, trapping him in the inferno, burning him. Lucifer growled as he was blasted away, but he knelt on the ground and endured the attack. With little effort, he stood up and brushed the dust off his fur.
"You're pretty smart." Lucifer smiled, he really meant the compliment, but then he focused, and a yellow bone of Aura, at least one meter long, appered in his hands. Suddenly he disappeared into the night with Extremespeed, then appeared right behind the Houndoom, striking him with the bone, whacking him away, then when he was in mid air, he held the bone high above his head and hacked him, punching him onto the ground. With the bone he was more capable of dishing out damage, and the bone could defend him pretty well if he used it right.
His spikes on his hands turned into purple claws, and he dashed towards the Houndoom with extremespeed, and before he could react, he did an uppercut with his shadow claw, bringing him airborne again. When he fell, Lucifer didn't let him go and unleashed a series of attacks with Close Combat from below, his last attack punching him into the air. Then he took a deep breath and fired a flash cannon towards the Houndoom with perfect accuracy.
