Each of these two characters is an evil twin from the futur. They have immense powers and have not existed for more than a few pages.
As a reminder:
Evil Gwenpool have CoMIcs Manipulation. She is aware that the world in which she exists is a comic book, and is able to interact with these comic book elements to a variety of effects; for example, she is able to step out of and between panels to facilitate travel between great distances and even backwards or forwards in time, to throw others into the "void" beyond panel borders, or to interact with scene elements such as word bubbles or sound effects.
Evil Access has the ability to create and use interdimensional gateways between the DC and Marvel universes to teleport himself as well as summon others to him. He can merge two people he touches if one is from each universe, creating an "amalgamation" of the characters. The gateways also permit travel in time when crossing universes. He can feel the presence of anything from one universe which is present in the other.
No preparation, No help.
