... Lefty Sonic: ~ Withered Sonic "Force-Up!" ... You coming with me! :D
*grabs his ear with some hidden karate art skill*

Withered Sonic "Force-Up!": ~ Oww... Lefty! My ear!
Where did you learned that?! I can't move!

... Lefty Sonic: ~ Just in case that you won't slip away till we get to my shop...
And you are gonna Sit there, got it?! :)

Silent (The Player/Avatar): ~ LoL! Btw. ... Lefty Sonic!
Thanks with taking care of Withered Sonic "Force-Up!" for me! *snickers* xD

Who doesn't love a spoiler alerts??

I thought that what I show here, will be important in the Intro.
When you see, you will know what's going on.
Now I have showed what (full name not revealed yet)
... Lefty Sonic is doing in Fiercy Forces Version.
And so, everything is not said yet.
But you can see, what is the connection between:
... Lefty Sonic and Withered Sonic "Force-Up!" (including ... Lefty Sonic's Mechanic).
(A Reference Hint: Tutorial in Maniac Mania).

That would be it.

Thank you for your attention!

Right, I'm going back onto the Intro.
