Still no idea what I will declare for the morphing call itself, but what I have created for after morphing is, "Striker Red, Engage! Power Rangers Strike Force!" and so on and so forth. Let me know if you like this or not.

@ProPro I've seen clips where they morphed via just holding the device and saying their call. I didn't watch SPD despite the great reception I heard it had. I have no real bias for or against a cell phone-like device, but inputting a code into it to unlock it puts a bit of a damper on the epic factor when they need to look down and dial it in. Space wasn't terrible, but morphing was a downgrade. You went from it being a very physical thing--combining two devices to form one, using a key to access the power, and simply just holding onto the device and accessing the power by calling on your chosen dinosaur--to "Please stand there as I press these buttons, one second."
If I wrote an oppressive villain with no honor, he'd be attacking you guys before that went off. None of that 'magical dodge despite you not moving' stuff.
