Power Suggestion.

Tinker/Trump: Tinker builds and improves a bulky set of powered armor, with other specialties being available later down the line, once Tinker has done research and collected data. Other paths open to the Tinker include generic scanners, workshops, computers, AIs, etc.

The powersuit's capabilities are initially basic and unimpressive, but as the Tinker scans parahumans, they can give the powered armor abilities based on the powers they've scanned. E.g., scanning a pyrokinetic blaster might allow the construction of a flamethrower, and scanning a clairvoyant thinker might allow the addition of long-range scanners. The powered armor can have a large number of power-inspired capabilities built into it, but only 4 can be used at one time. Switching between active powers takes a round.

Tinker can also create small (4' or less) autonomous robots or dolls in the style of the powersuit with one power each.
When the Tinker makes a doll, they can pick a power from their accessible set. The doll is improved in a way relating to the power.

Each power the Tinker scans can only inspire the addition of a power to the main powered armor OR to the creation of a doll. Once a scanned power is built into a doll or the suit, it can't be used again, and the same power can't be re-scanned to be used more than once.
