Godzilla

Godzilla, what else needs to be said?

King of the Monsters
The big iguana that fights shit and fucks over humanity but leaves space for new things to appear (because movies about a giant lizard fucking everything up need to have a positive side).

Season 5
The legendary king of monsters shrinked down to participate in TFR, or is it just a guy in a fursuit? We might never know.

Episode 5
Performs legendary run-in into Tazuna Joe vs Edward Richtofen match, getting thrown into a table and immediately leaving.

Later squashes Geralt of Rivia after his attempt to salvage his reputation.

Episode 9

Gets destroyed by Joe for interrupting his table match earlier. Godzilla kneels to Joe and they become friends.

Season 6
Joins up with Joe at his Joecoin emporium in selling wrestling merchandise.

Episode 6

12 years in the future, works for Tazuna Industries and defends the place along with a fellow furry.

Episode 13

Kojima books Joe against Agent 50 and Godzilla since it's funny, but a more adjusted Agent 50 easily defeats both of them.

Episode 14

Joe supports (and kisses) Godzilla in his match against Agent 50, helping him win.

Episode 15

Afterwards, Joe and Godzilla retired to make fujodimes and generally be pathetic by themselves. Episode 16

Reveals he was actually Tohru Adachi in a fursuit. Who's in love with Joe now.

Trivia

 * Single-handedly made a boring tables into one of the funniest matches in TFR by just entering.
