Star Trek technology is very advanced and it would be easy to market like the food replicator or in Alita Battle Angel with the super advanced robotic technology and to have the protagonist as a companion before the story begins so that it is easier for her to make the decision. to go with the mc and defeat the villain quickly
thanks for the chapter. the wishes yes could be better but they would make him to op and potentially ruin the story. for tech universe, mass effect,star trek, but i would suggest star gate. he just needs to get his hands on a couple stargates or knowledge to build them(ancient database) also beam tech, weapons, shields, possibly engines. for abilities go anime for the most part. like go to one piece get a logia then go back to dbz wish for weakness removal. can get companion anywhere just make sure it seems real for why theny leave.
