Cartoon Network has made an MMO, subtitled "Fusion Fall", which incorporates elements of all their different properties.
At first I only saw some newer ones like Kids Next Door and Ben 10 (as well as the confirmation that Bloo is appearing), but apparently in the trailer you can also see Dexter (who seems to be sporting a redesign?) and someone found Mojo Jojo.
It looks to be kind of like PSU almost, and if they include Smaurai Jack, that'll be awesome.
EDIT: changed pic to link, it's huge
DID I JUST SEE MEGAS
HOLY @#%$ I THINK I JUST SAW MEGAS
OH MY GOD THIS IS GOING TO BE THE GREATEST GAME EVER
HOLY @#%$ING @#%$, BATMAN
Wow.
Yeah, that's all I gotta say.
Whoa...ummm...life is good, guys.
If samurai jack is included lets hope that aku is fight-able, or maybe the scotsman.
The kids will like this. Heck, I may have to try this out too, being the MMO junkie I am. It can't be as bad as FFXI
