i really don't like the unique modifiers on these common turtles. Why the specific brothers??? They're supposed to work together, as a team! Helping each other out! in this instance, the only way for all four to get bonuses, you have to always stand in a specifically organized 2x2 square! Why?

So....if you have two distinctly different unique modifiers do they stack?

Can I place 003 donetello from the fast forces and modify Mikey's defense Value to a 19 or even a 20 on his second click thus giving him a 21 with combat reflexes? If so that's awesome

Yes, you can have all the unique modifiers you want as long as they have different names. You get 1 Ninja Power, Bro! and one Prudently Cautious.
