Luka

Luka is one of the main antagonists of Tai Chi Chasers, a member of the Dragonoid race and arch enemy of Rai. When the Tai Chi Chasers came to Earth to try and escape the Dragonoid's pursuit, Luka was drawn towards Rai's home and destroyed it, aiming to take out all Tigeroids he comes across.
