The development team and this community deserved better than this from NC Soft. Best wishes on your search.
For a general overview: Paragon Wiki. Each power name links you to a page with a list of pets summoned by that power and their powers. (The categories coming in Issue 24 haven't been fully added yet.)
For more gritty details: City of Data.
Thanks. Nothing that summarizes the powers of each pet?
Nothing I know of, not yet. Someone might have a spreadsheet somewhere.
It would be a worthwhile thing to summarize from City of Data, but I'm lazy. How about you?
For a list of each pet's powers, you have to click on the name of that power. (I usually just click on Core Superior and Radial Superior, because the powers tend to remain the same down the line).
Of course, if you want all the numbers, you can also check them out directly in-game, even if you're not level 50 yet. Just right-click on one of the power boxes in the Create section of the Incarnate window.
But no one-page summary that I'm aware of.
Edit: Until now:

Is there a guide that covers what each of the Lore pets does? Thanks!
