Well then. Mind telling me how you'd like your character to sound? Accent, dark, light, deep, lower, etc.etc. If you have a link to anyone with a voice close to it just so I get a decent idea, it'll help a lot.
This was harder then it should have been to think of really.
http://www.youtube.com/watch?v=EcA5CUBJlFw This guy could be used as a starting point, but not quite as deep. Basically, Northern English accent, quite rough, sligtly (But not too) deep.
It's also worth noting that of his three robots, Bolt (The flyer) makes beep boop kind of noises with his shield making a kind of Star Wars lightsaber style noise when deployed, DT (The Sentry) sounds like the Team Fortress 2 level 1 sentry gun and Steve-O.... is a hammer and doesn't really make any noise...
Specifically, it's the accent of the Manchester area. But yeah, the accent is in that style (Though I can't think of someone on TV/Film who has a similar accent that's not quite as deep, so that's the best example I can give I'm afraid).
