Could have picked X's Ulimate Armor or Falcon Armor in X5. Ulimate Armor is totally legit in X5, and it allows X to use Nova Strike whenever he wants and he'll be invincible during the attack, not to mention it deals out huge damage.

Or Falcon Armor, allowing X to fly, (actually flying not hovering) and invincible when flying, can damage enemies in contact.

But thanks for the compliment, I will try and keep up my activity during my two weeks of Final Exams...
