Ah, Evil Con Carne. Anyone else remember this show? It was overshadowed by its cousin-by-the-same-creator, The Grim Adventures of Billy and Mandy, which was (in my opinion) still really good but not even close to Evil Con Carne in terms of awesome. It worked really well when it was both shows in one way back in the day, but for some reason as seperate shows Carne flopped and Grim flourished...
If you haven't heard of this animated slice of win, it centers around a brain in a jar with a Mexican accent [Hector Con Carne] attached to a Russian circus bear [Boskov] (yes, you read that correctly) and his two 'sidekicks' - a female mad scientist [Major Dr. Ghastley] and a British-sounding military general [General Skarr, my favourite character!] - trying to, you guessed it, take over the world (M. Bison: OF COURSE!)! Much like my perennial favourite, the Keroro Platoon, they, well, fail at it. Fortunately, they never fail at being awesome.
I recently found a whole bunch of episodes on a website called 220.ro (link goes to a random episode), not quite the whole series but enough to keep one satisfied who misses the show. Viva Con Carne!
