Pick as many as you want, can involve yourself or others.

Extreme Enigma winning CITV

It's probably not my all time favorite but it's one that should be mentioned

DeDeDe vs LC at PFP 5, the end of the enterprise and Fan had to step down as VP of EAW.

Personally: my cash in

For someone else:  Hades winning at PFP 7

EE Vs HBB at P4P the entire match isn't talked about as much as it should be but its the reason I joined and it always stands out to me and I even go back to it when I write matches

My most notable moment would be defeating Cleo at Pain for Pride 6 for the Vixens Championship. I had always wanted to win a title at Pain for Pride and it was a great moment.

My favorite moments that do not involve me would either Vic Vendetta cashing in the 24/7 on Norman Hellion who was competing at Cash in the Vault at Pain for Pride 7 or Battle of The Gods I which led to Mikado Sekaiichi being in a wheelchair for like three years. The match was a great moment, but Robbie being in a wheelchair was not.

Probably more moments, but I can't think of anything else at the moment.
