Batgirl (Cassie) vs Sage

Battle of the analytical martial arts.

Batgirl with her ability to read/learn moves from opponents.

Sage has all her MA skills plus the ability to analyze & counter her opponents using her computer mind.

I'll admit that I haven't read a huge amount of Batgirl, and even less of Sage (wikipedia claims she has Wolverine-level MA??) but from what I've seen the matchup is interesting.

Batgirl

Sage. Easily, in my opinion.

Cassie wipes the floor with her..

Sage. Easily.

Evenly divided opinions, and both sides predicting an easy win. Interesting.

Sage thinks

There is her weaknes

Stalemate they would both cancel each other out, and call it a day.
