It would seem much more logical to use them in the film after this..I dont know much about them but they seem to be on as big or bigger scale as the alien invasion in the first film...Thanos seems more suitable for a smaller conflict..compared to the master of evil ...also he seems to be have unfinished bussiness with what happen with the first film
