YMMV / Teenage Mutant Ninja Turtles (1987) S03E13 "The Ninja Sword of Nowhere"

• Hilarious in Hindsight: This episode features a ninja sword forged from Imported Alien Phlebotinum that allows the user to literally cut a portal for the user to travel with. Wouldn't you know it, Leonardo from Rise of the Teenage Mutant Ninja Turtles ditches his twin swords in favor of an Ōdachi (basically the Japanese equivalent of a claymore) that can also create portals. With the reveal that the yokai that helped create the sword were created from Krang mutagen, Leo's sword can also be considered to be made from Imported Alien Phlebotinum
