We know former 'Xena: Warrior Princess' star Lucy Lawless has still got it, but on Monday morning she lived up to her surname after being arrested protesting aboard an oil-drilling ship docked in her native New Zealand.

Lawless and five Greenpeace environmental activists spent four days atop the windswept 174-foot drilling tower of a Shell company rig in an attempt to keep the vessel from leaving to do its dirty work -- drilling five exploratory wells in the Arctic -- and to raise awareness about oil drilling in the region.

The 43-year-old actress, best known for playing the title role in 'Xena' and for starring in the Starz series 'Spartacus,' tweeted about the protest throughout the weekend and told the Associated Press:

"I've got three kids. My sole biological reason for being on this planet is to ensure that they can flourish, and they can't do that in a filthy, degraded environment. We need to stand up while we still can."

Imagine arresting protestors and one is 'Xena.' That's got to be a little shocking. Now, Hercules, he looks like a protestor kind of guy.
