Dragon Shiryu is a proud warrior who never underestimates a foe. That would have probably been Bastila’s only chance as otherwise there is no way to stop this Saint of Athena. Think of Shiryu as a pocket Goku. Shiryu has super strength, speed, energy projection, and super durability. Trying to inflict any damage on him is effectively futile. His speed also makes this a non issue as there is no way Bastila will be catching up to him. His weak point is only accessible for a fraction of a second and otherwise Shiryu is virtually invincible. Dragon Shiryu wins.
