Rei- hates men. Her dad was a bastard, the one guy she did like married for political reasons. She promises her chasity to moon.
Venus- Most competent senshi after moon. Less on an airhead. She was the leader of the guardian senshi. Best kill count after Usagi.
Uranus-bisexual and wears dresses and men's clothes equally
Hotaru- a cyborg who was badly hurt in the fire that killed her mom. The Outers had a much better reason for wanting her dead in the manga. She was going to die because no matter the situation because of the damage her body sustained so they wanted to kill her before Pharaoh 90 or Saturn could be awoken.
Usagi-much more competent. She doesn't reset her personality like the old anime.
Setsuna- manga focuses more on how lonely she was at the space-time door and what Chibiusa's friendship meant to her.
Chibiusa-much less bratty.
