Mechanic IGN's you've seen that you liked?

I wasn't planning on making a Mechanic until a friend brought up the fact that I could try cosplaying as Tron Bonne or one of her Servbot minions from Megaman Legends.

So I was surprised when the name 'Servbonne' wasn't taken yet.

Haven't really seen any good mech IGNs during the past half hour of playing around with my new Mechanic...
