Well, you said you wanted a character with strong defense right?
Extra Amazing Save powers might be useful, or toughness. You might want to look into a form of healing or regen based on accelerating time around a wound so it heals faster. Maybe some skills/skill feats with the idea that you always have plenty of time and thus do a better job. Maybe a cheap Time-skip power, Time Travel with a short "distance" (so very few ranks) and foward only flaw. Maybe some temporal duplicates. Fatigue or Paralyze might work too if you can get them as power stunts.
Of course, I don't have the book, so my ideas might not be very good. I made some characters over break and took them with me, so I only had to edit my character a little bit.
