Insects have great strengh mostly because of their volume to area ratio, if you increased their size too much they would be in trouble even trying to move, though superhuman powers often look more supernatural than anything so maybe...
There exist a lot of applications for the exoskeleton though which is a big part of their strength. A lot of lessons in structure to be found in the insect kingdom, similar to how he uses the mantis mechanism for projectile launchers instead of just punching.
This also is a good reminder that MC is actually smart and has high levels of curiosity, even if he doesn't show it a lot of the time. Without any formal training, he is able to adapt to anything. He has extreme mastery over his powers.
Actually i don't even think we can rely on the biological side of things anymore, on his 3 evolution Mc can have "bones hard as diamond and flesh hard as steel", this is just insane, at this point he just uses the biological structure as a framework and only because he is worse at shapeshifting than Ella.
Yea, and he has so much strength that he can casually break through thick metal. I wonder what he will manage to do with the exotic materials found in monsters.
I personally disagree thought that he is worse at shapeshifting than Ella. She is better at changing others but I can't remember an instance where her forms were pivotal in a fight. Hiding a mountain of flesh beneath the ground doesn't count and MC can do that too by hiding tentacles underground. Both times, when she revealed her underground forms, they got smocked, by Nico and Nyx, and her tentacles are hardly more powerful than MC's even if she can create more mass than he can due to being higher level.
Additionally MC since his third evolution has shown exeptional ability to work with materials and thanks to his memory powers, all his creations are perfect. His forms are a true extension of his fighting style, and he uses them both for additional power, and for controlling the environment with strategy/traps. Ella relies mostly on her regeneration, maneuverability and transmutation. Her trick where she makes her form immutable is quite an impressive one though. Still, it's a level 5 ability and who knows what the MC may unlock by then.
Still Ella is quite impressive. Being able to craft functioning forms without the gift of memory must have been quite an ordeal. MC is really lucky in this regard. It's way more efficient to work on a structure that you understand innately, than building something from the ground up.
But maybe with his memory powers he will eventually be able to transcend the individuals and reach the ancestors through their DNA, touching a lizard to reach a dinossaur is something i can imagine happening.
I expect that his memory powers will be the main theme of his third evolution. I wish for them to manifest in a more mystical way than just through touch but in any case I hope that really cool things will come from it.
He is already quite adept at reading genetic memory and long term memory. It may very well be possible to read the evolutionary journey of species.
