Suggested by Sonic Phantom (MAR) is very powerful and one of the strongest fighters in his verse. He’s versatile and has some of the best ARM weapons. That said, Furuichi drank a potion that gave him incredible powers and for a while there he could even keep up with Oga. That means his speed is enough to dodge Phantom’s attacks and he has enough power to put the guy down for good. That’s why Phantom won’t have a chance in this fight. Furuichi wins.
