My friends and I made comprehensive respect threads for a number of psychics in the X-Men franchise. All feats are shown with scans and context, and most have citations/issue numbers. Feel free to check them out.
Please note that we had in making the RTs was to properly show what each character is capable of and not to just throw in everything they've ever done so we leave out stuff that we felt wasn't necessary to include (especially with more prominent characters with a lot of feats)
