Here's what my idea is: He's a Thinker and semi-Master.

This new character gains a shitload of knowledge, evenly spread around to varying subjects in his mind. To simplify it, he knows a general good amount of shit about a lot of topics, excluding 2. He gained a large amount of knowledge based around Strategy and Hacking, so he has insane intelligence of tactics that can be used in another person's favor, and he can hack into a lot of things on his lonesome, but he cannot do it in person or act on it in person, rather relying on how he is a Master.

He has one reliable method of communicating with the outside world, which is basically a tiny flying camera that is very resilient. It has no combat potential other than distraction. He has a setup in his bunker (that has 2 sources of renewable energy powering it) that allows him to connect to this camera and see through it on a live feed. I categorized this as him being a Master as it took him a long time to make this, and it can probably be made by engineers and scientists. He also only has one of these cameras, considering in it's planning stage he almost lost another body part. 

I'm still thinking of possible limitations for him but right now it's mainly dependent on having only one of these cameras.

tl;dr - Insanely strategic guy cannot fight or reliably get in harms way, so he uses a drone for his way into the outside world.
