Derrick J Wyatt has posted a new piece of art on his blog for his April Fools joke. It depicts a bunch of characters, some of which are in TFA Season 3, and some of which are not. The challenge, according to Wyatt, is to pick which ones are appearing!

In it is:

Rodimus Prime
Sky Garry
Grandus
Animated Personality Vangelus
Huffer
Pipes
Botanica
Tap-Out
Zaur
Slapper
Sundor
Flip-Sides
Target Exclusive (True Colors) Shockwave

I'm guessing Rodimus Prime, Grandus, Sky Garry, Slapper, Shockwave, and Vangelus.
