Do you even understand how f**ked everyone is. Century long calamity Inkmatas has the power of the Creator because of the Omega Ankh, 100% collector would need a miracle to win
You're forgetting... Eggyhead for one is equivalent to Inkmatas in her normal form, second, ultra Egg-stinct alone is roughly equal to 100% Collecter, third, he has the power of creation, Redis staff, and Inkstone, along with ultra Egg-stinct.
Century long calamity Inkmatas should be considered non canon because of this but, In this form she has double the power of the banisher, you heard me right, double the power of that mf. She has the power to level one half of the multiverse with calamitous power, so long story short, Century long calamity Inkmatas wins
