3x28 - MegaMan NT Warrior

Lan becomes tired from constantly battling the Neo WWW, so Dex decides he wants to perform CrossFusion and help in the battle. He confronts Famous who uses Rush to create the Rush SynchroChip to help make it possible. Dex and Maylu accompany Lan to a dinosaur theme park where Viddy strikes, but Lan is too tired to battle. Dex attempts CrossFusion and fails, so in order to save the day, Maylu tries it. Surprisingly, she CrossFuses flawlessly and helps Lan defeat Viddy.
