The Pokemon TF 3rd season starts in June 2021.

Three weeks after the unheard incident of six people last seen in the college play, many transformed Pokemorphs were forced into hiding, following the city government ordering a lockdown in search for missing people. However, no authority was able to figure out where radioactive tubes came from, as those tubes were a bit increasingly smuggled from the abandoned lab, formerly named Arsimov Radioactives Incorperated Research Laboratory. There was one instance here, operated by three guys, but this transformation also caught onto two unknowing by-passers.

Part 3
Damian: You! WHAT'S THE MEANING OF THIS?!
Vanilla: Finally! I'VE REACHED MYSELF TO FULL POTENTIAL!
Damian: ANSWER MY QUESTION, DAMMIT!!
Vanilla: Woah woah chillax! Let's us celebrate our new forms!
Damian: By smashing everything in our path?!
DJ: Dang Terry, you look stunning!
Terry: Yep! Can't wait to kick some butt!
DJ: Yeah and we'll end up kicking people like football
Terry: What about cars and tanks then?
Johnny: Well, this is new. And have you guys seen my friend Timothy Soro?
Vanilla: Wait, you're his friend too? This seems odd, but first of all, why have you come here?
Johnny: Because he asked me to get that black box you guys have.
Terry: Oh, our client will be pissed at us about this then.
