Monsters that Should Fight Godzilla and Kong in 2020

Since Godzilla vs. Kong maybe announced that Godzilla and Kong might team up to fight someone or something that's a threat. And basically, the monsters that is so tough and dangerous enough to fight them both. These are the decisions. And King Ghidorah cannot be on this list, because he's already gonna be in Godzilla 2: King of the Monsters 2019. So which monster would you prefer the most to see in Legendary MonsterVerse's 4th film: Godzilla vs. Kong?
The Top Ten
1 Destoroyah

Destoroyah should be the one I think is gonna fight Godzilla and Kong. He's been mentioned so many times.

2 SpaceGodzilla

Spacegodzilla is the heavyest monster it could bust godzilla and kong

3 Bagan

He's a Monster that appeared in Super Godzilla on the SNES. Toho really wants to put him in a Godzilla film. I think Legendary might do it.

4 Monster X

Monster X is pretty strong

5 Hedorah
6 Biollante
7 MechaGodzilla
8 Gigan
9 Orga

Orga should clone into godzilla and destroy kong

10 Megaguirus
The Contenders
11 King Ghidorah King Ghidorah is one of Godzilla's most well known enemies. First appearing in 1964's Ghidorah, the Three Headed Monster, he has gone on to appear in more films than most other Godzilla foes.

Please let this be a remake of invision of the astro monster but instead of rodan it's kong

Bring him back

12 Gamera Gamera is a giant monster or daikaiju originating from a series of Japanese tokusatsu films of the same name.

We would have the 3 most iconic giant monsters in one movie

13 Mecha King Ghidorah

Just incase king ghidorah dies on godzilla: king of the monsters, they bring him bigger, better, and stronger.

14 Mechani-Kong
15 Battra
16 Baragon
17 Cloverfield
18 EVA 01 - Evangelion 2.0
19 Wolfman
20 MUTO
