Well he can do these:
Consumption: Malesgrow can absorb anything including matter/energy, power, concepts, etc.. He removes it from the source into his body and use it in various ways to gain some form of advantage: by enhancing himself, gaining the drained power or concept, using it as a power source, either temporarily or permanently. Malesgrow's entire body is also made of a substance that allows for eternal consumption, allowing him to absorb anyone and anything that makes contact with his body without him needing to do anything.
Cosmic Creation: After the first "mating" with the Cosmic Human, Malesgrow is able to use the same biological formula to create more kids out of his own Cosmic Essence and was able to consume them, gaining even more power while at the same time not losing any upon making them.
Cosmic Evolution: Malesgrow has the power to be in an endless state of transcendence. This transcendence allows him to gain a power boost that allows Malesgrow to view his former power prior to the transcendence as nothing more than what could be described as fictional.
Eye Beam: This beam that shoots from Malesgrow's eye can devastate and destroy multiple Transvoid Multiverses and reducing them into absolute oblivion.
