Crime busters: Charlton Copycats

Two obscure worlds with equally obscure heroes, known as Earth-Four and an Earth in an adjacent Earth within the Watchmen Universe. Their parallel are remarkable!

The preeminent teams of each world, the Sentinels of Justice and the Crimebusters, did not have long tenures. Their members mostly operated separately or in smaller teams as fabled "Action Heroes"..

For instance, Captain Atom and Nightshade had a budding romance that blossomed during their adventures as had Doctor Manhattan and Silk Spectre. 

Other dynamic duos such as Blue Beetle and Question handled more street level crime as had Niteowl and Rorschach.

Then there were those who worked mostly on their own... the cerebral athletes Thunderbolt and Ozymandas a prime example... as were weapon wielding warriors such as Peacemaker and Comediante. 

These champions were the latest to don colorful costumes, and were preceded by an earlier generation birthed during the Second World War. Perhaps most notable of those first heroes were the original Blue Beetle and Niteowl who inspired their successors directly and others by example.

Other golden age gladiators of good, such as Earth-Four's Judomaster, Tiger, Captain USA, Superguy, Green Spider and Yellowjacket mostly did their own things.

Conversely, the longest lasting leagues of legends in the Watchmen realm... the Minute-Men... assembled such golden oldies as Captain Metropolis, Hooded Justice, Dollar Bill, Moth, Silhouette and the first Silk Spectre into a tenuous team.

Joining them. were the first Niteowl and Comedinate, and combined were longer lasting than the original Sentinels of Justice composed of Helio, Mentalia and Brute that took orders from federal agent Sarge Steel for a brief period of time during the modern age of manhunters.
