Mega Robo Bros 3: Mega Robo Revenge
Alex and Freddy are brothers...robot brothers! And they bicker and squabble just like any other siblings. But that's nothing compared to the fight that lies in store for them. They discover that they have an older brother they'd never been told about, called Wolfram, who everyone thought had been destroyed. But Wolfram is back, and he's out for revenge. Revenge against all the humans who tried to obliterate him. And there's one human in particular who Wolfram has targeted for revenge... Alex and Freddy's Mum! Can the Mega Robo Bros stop Wolfram and save humanity?
