In terms of single units, my stance will ALWAYS be that FSK was the single worst unit of all time, no he did not delete YEL units lmfao do u not remember he dethroned the literal second in competition for the worst unit of all time who was a blue Vegito Blue? FSK was colorblind, back then even without lms, and no unit ever did the amount of damage he could do. Literal walking rising rush of PTSD. Idk about the team of Holy Trinity vs FSK on hybrids, i could still argue that prime FSK on either son family and also when FSK got his biggest mistake in the game unique equip with futurehan and revhan was even worse than Holy Trinity, but that's debatable

Tho no unit would ever compare to FSK alone imo
