Interdimensional science and technology starting from cyberpunk

"Technology changes lives and makes the world a better place."

Lear, who firmly believed in this sentence, died of nuclear radiation and began his journey through different worlds--

"The fault is not mine, but the world's. Let's start by defeating Arasaka."

"What a powerful cybernetic body. Fortunately, my Cybertronian cybernetic body is not bad either."

The main world is probably Marvel, with a higher limit and more freedom.
