yea, you can include all them

and for the speedy person and the person who can shrink, only use those powers in instances like these: the person who can shrink can only use them for attacks lets say, not for the running and idle and jumping etc cuz it will be hard to control the character and it will be hard to fight against the character

for the speedy person don’t make them super fast as again it will be hard to control him and fight against him, but in his attacks you can make his fist move fast or something
