Well you could if you wanted to. It's been seven years since Series 7 and as Calum said, does anyone know if they've been active? It was quite a nice clusterbot (well, I would say that, being biased towards spinning drums) but compared to Gemini, they looked really small and terribly underweight, even though they were almost the full weight.

So I'm sure there probably wouldn't be a problem calling your machine Black and Blue (although I think there was an old featherweight called that too, but again it's been a long time since that's been about). Alternatively, I don't think the name Bruiser has ever been used. I had it as a name for a robot I designed for Rex's Robot Challenge but it never progressed beyond a drawing, so didn't get used.
