I thought so Immortui likely has different ways to fight and counter different things. Hence why some like Sil with a lot abilities has an edge. If Immortui blocks physical attacks Sil uses energy or element attacks, if he uses his colourless energy Sil teleports away.
Ray strength is just above all else. there is a reason the author didn't allow Ray join the team. him alone can beat up Immortui. so what's the need of having him.
