Review Detail of Dio99 in Invincible's Twin

At first I was really loving the story and his unique ability but it kinda ruined the story when he killed both mark and omniman. Like I somewhat understand him killing Omniman even though there was probably a way to solve the issue without killing him but mark killing eve was completely random. Especially when he should a have been helping his bro out at that moment or at least trying to stop the fight or something. Like mark wouldn't sit back and watch his father and brother kill each other even if he is weak. I feel like that chapter was just extremely rushed and out of place but I enjoyed the story before then.👍
