League of Extraordinary Historic Heroes

I was thinking about this the other day and thought I would share it with you all. Upon much consideration (about 25 minutes worth), I've assembled a league of extraordinary historic heroes. If given the opportunity, I would assemble these people and we'd travel through time righting wrongs and fighting evil.

Team Leader: Henry Clay

After being denied the Presidency three times, Clay is devoted to proving his ability to lead. A great compromiser, he easily diffuses conflicts within the group without lower morale. Quick to use his words before his weapons, Clay stays cool in almost all tough situations. Known enemies: Aaron Burr, James K. Polk and John C. Calhoun.
While in the field, we have a separate leader, kind of like the assistant but she gets her hands dirty (like Cyclops in X-men):

Field Leader: Boudicea

Boudicea is known for her ability to take on large foes without question. Standing up for those who cannot stand up for themselves, and having a penchant for fire. Strong loyalty to friends and family. Known enemies: The Roman Legion.

3rd in Charge: Tecumseh

Known for his samurai skills and his ability to organize people in battle, Tecumseh works well as back up to Boudicea's in your face leadership. He always knows when to utilize his team's strengths, but is quick to push people beyond their limits. Has been known to take risks. Known enemies: William Henry Harrison.

Weapons Expert: Annie Oakley

Prefers the .22 caliber rifle but is well versed in all types of projectile weaponry. A dependable ally who always gets her shot. Keeps a level head and is not put off by competition. Known enemies: William Randolph Hearst, Lilian Smith, William McKinley and Pernicious Anemia.

The Big Brain: Leonardo da Vinci

An artist, inventor, genius and player, da Vinci helps the group by bringing in new technology to help them in their missions. He often stays behind to make sure the team is directed across space and time correctly (his invention of course) and because he tends to create more mischief than assistance when he interacts with civilians. Due to his charm and likability, he is occasionally brought on mission to be a peacekeeper. Known enemies: none to date - everyone loves this guy, some people, a little too much.
Obviously there are many heroes throughout history, and some of these people would be called on as consultants or mercenaries for specific missions, but this is my core crew. If you had the ability to establish a League of Extraordinary Historic Heroes as I do, who would be on your team?
