Just want to comment Batman usually fight bare hand, use a lot of gadgets, intimidate and psyche/out think his opponents. If you really want to role play as rich boy in Underrail, the obvious route would be a bare fist build, use lots of combat utilities (throwing knives as batarang, flashbang, chemhaze nades, etc), obviously takes Intimidation skills (and Yell) + maybe TC: CC only - frighten, enrage, mental breakdown, Neurovisual Disruption) but not using any direct damage abilities (NO, bilocation, Psi-cognitive Interruption) as a "regular" peak human w/o super power is his thing.
