There are clips from foreign CN eps that are out from That's The Stuff, and of course the Alien Madness promo (that we didn't get to discuss because of the awkward glitch on the site)
Chances are the aliens for That's The Stuff are Grey Matter, OE Four Arms and OE Diamondhead.

Episodes 22-24, aka the episode list I sent above are now up on the CN App and CN Website, they also feature episodes with Shock Rock.

For the first time since Omniverse, the US may be getting episodes before anyone else.
Mon April 16th - 6:00 PM (EST) - 222 - Half-Sies
Mon April 16th - 6:15 PM (EST) - 223 - Xingo's Back
Mon April 23rd - 6:00 PM (EST) - 224 - Bounty Ball

Apple and Onion wraps up its finale tonight with a marathon of all its episodes.

Two more weeks before the 11th Alien airs in the US, for those who have yet to see the special (I'm assuming everyone has by now) who's hyped?

So for the last few days, I bet users like us have noticed the site has been down. We don't know why it was down for the last few days but all we can say is... we're back! So let's keep the party rolling!

Well I mean the description and the news presented confirms Shock Rock is going to get Ghostfreaked, which explains how Upgrade returns in the Omnitrix, so yeah.

I'm surprised no one has talked about this but CN's Upfront is out... and.... Shock Rock is getting Ghostfreaked

Greenlit for a third season, Ben, cousin Gwen and Grandpa Max are ready for action that will be loaded with epic transformations, never-before-seen aliens and foes, and with high-energy vehicles to kick hero-time into maximum overdrive. New episodes from the current season, including a half-hour special will introduce the newest alien trying to invade Ben’s world – Shock Rock, who is looking to conquer the world and drain the planet of energy and resources. Ben 10 is produced by Cartoon Network Studios and created and executive produced by Man of Action Entertainment.

Also thanks to some insider info, so.... we are getting new aliens, but with how MOA wants to do things, basically while Upgrade takes Shock Rock's slot, some other new aliens will take other alien slots, keeping Ben at 10. Also new gimmick...?

Hilarious @Ungrateful-Wolf
and Some surprising info leading to the season finale is revealed, also the 11th Alien will premiere Friday April 6 for the US
