Pretty big energy blast that Pegasus Koga seems to be firing right? He is definitely a formidable opponent, but Bass’s Earthbreaker could definitely top that one. Bass also has the edge in close quarters combat and his energy defenses are the best in the biz. Bass wins.

Bass already fought him
Orion is definitely a tough fighter though
