This month on The Flashback Cartoon Hour, Nick and newcomer Matt K. plunge head‑first into one of the most stylish, atmospheric, and criminally overlooked anime of the late ’90s "Blue Submarine No. 6." From its groundbreaking blend of 2D and early CGI to its haunting underwater world, we break down how this four‑episode OVA became a cult classic that still hits hard today.

Whether you watched it on Toonami, rented it on VHS, or are discovering it for the first time, this deep‑sea dive is packed with lore, laughs, and plenty of Flashback‑style chaos. Grab your pressure suit — we’re going underwater.
