Right Charlie wrote: I think its real name is The Ruin, as NK had a Clan Challenge called "Ruination Race" that required the winning Clan to "kill 10,000 Ruins". As far as I know, there was a Clan Challenge called Ruinous Race, requiring the winning clan to destroy 25000 Ruins, which were the final bosses in the game SAS:TD, not BSM2.

There aren't any really "real" names for the bosses, so I guess it's just up to the community to decide :)
