- Godzilla vs. King Ghidorah (1991). The two title monsters have a battle in Tokyo which ends with Godzilla blasting off King Ghidorah's middle head.
- War of the Gargantuas. The brown gargantua is a good guy who likes and protects humans. The green gargantua is violent, savage and eats people. They are brothers who were raised separately.
