It looks like the marines just lost Leo and Shinobu's support if they are going to execute Ace due to who his father is then they better be prepared for his wrath. I know Whitebeard needs to die due to age and to further the plot but could you save Ace at least? Also if you are going to give either of them a devil fruit ability then could it be: Leo - Soul Soul Fruit / Tremor Tremor Fruit Shinobu - a plant based fruit ability so she can grow her own herbs to use in her medicines and poisons, this was she will be a true threat and a walking pharmacy. All she needs to do is have a pouch of seeds to carry around with her and bam.
Why don't they attack the Big Mom Pirates? They lost two sweet commanders, Katakuri is injured, Daifuku and Perospero were also killed in the last chapter, and many of her pirates were either injured or killed during their attack on Impel Down, including Big Mom herself. The Big Mom pirates are significantly weakened now, whereas the Whitebeard Pirates are not. They still have many of their commanders and whitebeard is still very strong.
