Do we HAVE to visit Gennai while we're there?
We jump straight into the action (not even an opening sequence!) in episode 39 - The Battle for Earth, JP title "Two Great Ultimate Evolutions! Destroy the Darkness!", DVD Title "Two Worlds Put Together"
Along the way: Joel's very rude interruptions (so rude), the amazing portable television, crotchfaces, Birdramon's horrific screams of pain, and goodbye to the real world arc.
