last chapter?

It will not be op, if his adaptation only gets boosted only when in danger ( Temporary ), So when danger is over, he'll return to his original state. ( Fast evolution will result in mutation, which will make him look ugly ) so he'll get self conscious, so it's not op.

Just wish for doomsday template, but upgrade his adaptation to scp 682 level.

You can make him adapt & evolve, depending on the situation. For ex - His adaptation speed will increase only when in danger & he can resurrect, so what kills him makes him stronger.

Adaptation & Evolution would be good

where is his system ?

DC is a hotspot of - expect the unexpected, unless he has reality manipulation on multiversal level.

Why he's giving away his identity, Author?

so he can hide his powers from hero & villains

Why he doesn't have any bodyguard around, if he is rich?

Humble the oans

Why is he taking disrespect from heroes? just humble them in their place.

Mc doesn't have any goals

Finally some good thinking

So he wants to remain hidden by flying over New York with shield capturing his identity via satellite.

How can he say he's OP, For example Franklin Richard he can manipulate reality by the time he's teen.

For having absolute intelligence, he's very stupid.
