Suggested by Sonic Zero has his Z saber and multiple lifetimes worth of experience. That said, he isn’t going to be ready to duke it out with someone like Yusuke here. Yusuke has the massive edge in power and speed. As good as Zero is, his durability also isn’t quite up to par with Yusuke’s. When a robotic part is destroyed there is no coming back from that and Yusuke hits with the best of them. Ultimately this fight will become worse for Zero as it goes on. Yusuke wins.
