Well I can instantly think of Aveline de Grandpré. A privileged girl at a young age in Lousina but one day tried to help a man who was enslaved and the assassin brotherhood trained her from beyond the wrist blades. Eventually made good use of the whip for combat and getting around like Indiana Jones

Even Optimus Prime would stand and defend innocent people from ICE. Immigrant and U.S citizen. As he and the other autobots were immigrants themselves after Primus shut down to survive as a result of the war on Cybrrtron. As OP said it "Freedom is the right of all sentient beings."

Kind-hearted. It's fitting

The Abbey in Marvel's Midnight Suns. Despite the occasional spirits moving around, or the demon within the Forge, as well as any nearby night terror, it's a cozy place

Tron Uprising is something I'll never forget. It was a great series but unfortunately was left in one season
