2x34 - MegaMan NT Warrior

Misaki uses the power of a Dark SynchroChip to CrossFuse, but as a side-effect, his human heart is enriched with darkness. Captured by the NetSavers, they begin to heal him, but Ms. Yuri reinstitutes his darkness, causing him to escape. Lan battles with Misaki in CrossFusion, but the battle causes Lan's PET to be badly damaged.
