Even if it is true that monster parents impact shiz it doesn't guarantee ultimate victory.
The MC despite having numbered parents has been defeated plenty of times via bad ends and even if you don't count those he still got his ass handed to him by other folks like Klaus who from what I can tell do not have a numbered parent.
The true king in the world of superhuman is "experience" so as long as you got that you should be good to go but having a lot of power helps too.
The MC has earned every victory under his belt due to him training constantly and learning from each fight by adapting new things. It is for sure that his growth would be a lot slower if it wasn't for his parents but even then he'd most likely gain everything he has now but at a slower rate (its pretty likely he would of died earlier on in the story if he had a regular monster as a parent due to his growth being too slow or rather, the normal growth if you will).
I'm pretty sure
Gtdead and
DrakoGhoul have talked about this very subject in the past in regards to the MC's growth being faster than the norm due to his numbered parents and gives credence to the idea that a monster parent impacts the growth of a superhuman.
Idk the exact rate of how the raised messes with the growth but I'm sure they might.
These are my thoughts:
The way I see it is having your monster parent be a DIRECT Apostle is luck of the draw. If you survive the encounter you SHOULD be stronger than most other Superhumans, not weaker. It's like an Elder Vampire gives you his blood and expect you to be weaker than most of the other normal blood vampires? Lol no. The same should go for having a parent that is closer to the source of the original (being an Apostle), example being the Fairy for instance or Aglaecwif, Valravn, etc.
As for HOW MUCH it effects your power level that remains to be seen. I'd wager most of the Lvl 5s now are probably not DIRECT descents of the Apostles, maybe some but most probably not (call it a hunch). If we were to see them at the Lvl of the elites however (The Captains), I think THAT would be crazy. The only thing they really have on the other Superhumans isn't their power, but their age and time nurturing their abilities for 80+ years. If nothing else, being a direct descent gives you a unique power stronger than that of most others around it. Malik seems like he just had a Fire ability, but the way he grew it through Evolutions, and the years he's HAD to do it (factoring in potential and allat) he made it ridiculously op, same for Bernhardt; as I doubt the last few numbered are the 4 elements this isn't Avatar.
Which brings me on to my next point; the other factors. We know some people are just BUILT DIFFERENT. People like us (MC), Alice, Henri?, and others that grow exponentially fast or have a unique amount of compatibility with their power. Alice despite being Lvl 1 and NOT a direct descent of the 6th has such a strong and pure power that trumps most around her. The MC has 2 abilities form 2 DIRECT Apostles, and is already Lvl 3 in the span of a year? Henri achieved Lvl 1 to 5 in the course of a week, the list goes on. But then there are others like Tiffany, who struggled with her ability and didn't try to put herself in more dangerous situations to grow it in a raw manner, yet she is an Artificial direct descent of the 8th. Michael could even FIND OUT what his fucking power was until after he achieved battle, but we KNOW Michael can use his ability outside of battle collecting energy, probably not the BEST compatibility in the world, perhaps the 2nd saw his raw talent for power and not his intunement (it's a real word now).
Anyways I don't have the energy to go over potential this and compatibility that. Some people are destined for Lvl 5, and some AREN'T (tree boi). But what I DO believe is that Michael and Tiffany rushed it, and Alice at this point is going to have a much better grasp with her ability in a fight compared to Tiffany who not only has a terrible handling on her ability already, but probably didn't even shape up what she wants to FOCUS on yet before already jumping the gun to Lvl 2, same goes for Michael. He discovered light bud energy suction and corpse energy, is there ANYTHING ELSE? Did you wanna maybe practice a bit more and experiment? Perhaps find any OTHER little abilities you've got hidden so that your Evolution can focus on one thing majorly rather than everything improving with little to no change (armors v JUST better Shapeshifting, tails vs JUST better tentacles, etc. etc. There's a reason our Memory Trait is ONLY getting it's first real cool move NOW rather than way back).
