The Authority are a VERY uber team.
Notably, the Doctor and Jenny Quantum.
Hawksmoore never really did anything too incredibly impressive, except when he merged with Tokyo.
Midnighter is a top street leveller, and Apollo seems to ALWAYS run out of juice - he definitely lacks staying power, 😛.
The Engineer is good, but not great. Her constructs don't seem too immensely powerful most times.
Rose Tattoo, as the spirit of death, seemed vaguely saint of killers-ish, considering that she could kill 'ANYTHING.'
Supposedly.
