These are some of Insanity Side’s forms that she shape-shifts into.
The one on the right is meant for speed and long distance air travel. The one on top is meant for stealth and sneak attacks. The one on the left is a giant form that can also fly and it’s meant to combat other giants.
Insanity Side has an other forms but these are her main ones because they require the least energy and focus to maintain.
