How to unlock the Brothers achievement in Marvel Avengers Battle for Earth - Definitive Guide
All the winning character achievements can be gained in versus mode. I'd advise you leave these selection of achievements until you've complete the campaign mode as 3 or 4 of them will unlock naturally from the battles you have to win. Also completing campaign will guarantee you have unlocked all characters.
Simply load through the menus, fight modes -> versus, select thor and loki and fight against your defenceless opponents.
