>>101035699Groot isn't even a baby anymore and hasn't been for months. The reason why Mantis isn't used is because nobody actually cares about her right now in the comics and there's plenty of characters already to juggle with, without having to include one from the movies for sinergy. And on top of that, the hardest pill to swallow is that Cosmic Marvel, while rich in content, doesn't have as many fans as the other properties let alone the movies, so fewer writers care to work on it.
