I too think the Omnipotent being would simply be beyond the concept of good and evil. They would be more concerned with balance and maintaining their design (that's if we are giving them a human characteristic). To them nothing is good or evil but instead they view things in order of necessity... example: people have to die so new people can be born, so murderers and natural disasters are ok. As humans we see that as cruel and evil but to this all powerful being it is just a means to an end. I am really oversimplifying the concept but I hope I'm being understood.
They would probably have the ability to overthrow other almighty beings or it would be a universe where the seat of power itself is the omnipotence and whomever holds that seat is the All-Powerful being of that universe. In any other situation I feel that the Omnipotent being would already know they were going to remove their limitation and prevent them from doing that.
The problem with this question is it makes Omnipotence seem like it can be defined as one singular being or force so it can be countered with an equally defined being or force. What we are all saying is there cannot be a counter force to omnipotence because ominpotence in its own definition covers every possible force, condition, capability, and complexity. It simply is everything so if you do have a singular, definable, "Omnipotent" being they would simply be a manifestation of an even greater, less definable, force.
Your question reads more like you are thinking of conceptual entities. There are plenty of conceptual beings that represent a single aspect of Omnipotence but even their counterparts are themselves just another opposite representation of Omnipotence (ie. life/death, order/chaos, time/space etc.)

Animal Factor: Meggan (She can basically link with nature and morph into stuff so somewhat Animal Man esq)
Energy Factor: I agree with Quasar/Nova/Captain Marvel/Dazzler/Gambit
Elemental Factor: Storm/Iceman/Human Torch/Crystal
Tech Factor: Victor Mancha/Vision/Ultron/Forge
There's no way I would keep all the powers. I think I would want some kind of device or object (maybe like Ben10) to where I wouldn't have access to all the powers at all times but maybe a choice few.
