Bond Manipulation:
Repair - To fix things by joining the bonds holding molecules together. Bringing broken things together and mending their bonds to fix them.
Limited creation -+ by joining bonds of different things, you can fuse or join two separate things to create/make one new thing.
Enhance - To enhance things by strengthening the bonds holding the things together.
Disassemble - To make things fall apart by breaking or disjoining the bonds holding them together. Opposite of enhancing the bonds. You weaken them.
The power is only bonds, not molecules so the person can't create things. There's no matter manipulation or energy manipulation involved.
Only manipulation of physical bonds between or in objects.
