I think that for surpass Bernie, Henri and Malik, MC and the Eye would need at least one of the "two" things the Eye has repeatedly said he needs, whatever they truly are, they fusing at MC lvl 5 might not be enough, maybe. As unusual for his level as MC is, the Trio seem to be even more freaky(Eye aside), Henri had evolutions back and forth for four nights, ending as Powerful as the Invincible Lord of the Alt Humans, all that without gaining any strength between levels or even embracing his nature fully, Malik and Bernhardt are on the same league as he is, even though they are just mutts(though, here might play what Syla said, about lesser spawns/mutts mutating in ways no one can expect, as an example of how Evolution can bring 'terrible' things), and they at level 4 were stronger than Elijah/Kira at their fifth, and the gap between 5/4 is greater than 4/3 level, for last the Eye itself in his last incarnation, mentioned how the Trio are things that shouldn't exist, he was utterly freaked out with their mere existence, this all to say, I think to reach their level, MC/Eye would need to do some heavy lift before, but yeah, I agree totally their endgame(of MCeye) is above Bernhardt and Malik, Henri though?, he's other deal since he might be Paradox halting it's own birth, as mentioned by the Eye, "Ascendant yet still unborn"
