Deathsythe: all forms. There's something about a giant, mecha being portrayed as the anthropomorphic personifiction of Death. Plus, the rest were all.....well, tried and tested ideas.
Wing/Wing 0: Transforming fighter/all rounder
Sandrock: Dual wielding, close combat
Heavyarms: guns, lots of guns
Shenlong/Altron/Nataku (whatever it was called): A remake of the Dragon gundam from G:Gundam. Literally.
Deathscythe: close combat, yes. But stealth capable and with a huge beam-scythe. What more could I ask for?
