Most if not all second gen Vault Hunters (i.e. BL2 and TPS) were so much more fun to play for me in comparison to any characters from 1 and 3, but Athena is my all time favorite.
Useful and well designed action skill, absolutely insane dps with elemental/maelstrom build, and even though I’m not a fan of melee in BL I found it pretty satisfying actually (better than Zero’s imo).
Also she’s just a badass, character-wise. No constant bragging, no unnecessary RL accents that just try to be funny too hard, and no random outbursts of insanity (edit: relative to standards set by other characters). Coupled with her awesome looks, which they really nailed in TPS. In addition, Tales made me like her even more.
