This is my ideas for the Mortal Kombat Chaotic New Era story made by you DP994 but I think it's best to finish the Tiny Toons series story first since it's been delayed a few times anyways here are my ideas.
Calamity tells Furrball and a few friends being Morgana Beavery Raccoony Hamton and Plucky he's downloaded this fan made game on the PC called MK Chaotic New Era which features the biggest roster he's ever seen they boot up the game and select versus mode their faces slowly turn to shock when they see the roster which causes Hamton to faint Furrball scrolls through the roster and to find any interesting characters and eventually he finds Chavo Homer Simpson Ronald McDonald The Undertaker Goku Shaggy Don Ramon and Lionel Messi of all characters.
Surprised by how many joke characters are in the game the friends decide to do a few matches together first Plucky and Hamton play as Chavo and Homer Simpson Hamton wins the match and performs a fatality in the game Homer throws a giant bowling ball which crushed the opponent and then starts laughing loudly while speaking Spanish for some reason.
Next Morgana and Furrball play as Shaggy and Goku Morgana wins the match and the fatality he performs is Shaggy running over the opponent with the mystery machine causing everyone to laugh to which Furrball says I love this game.
The next matchup is Calamity and Raccoony playing as Ronald and The Undertaker Calamity wins the match and the fatality is Ronald chopping the opponent in half with a giant French fry causing everyone to laugh again while Morgana says this game is amazing.
Finally Beavery and Plucky play as Don Ramon and Lionel Messi Plucky wins the match and the fatality he performs in game is Lionel kicking a soccer ball at the opponent's head and then screaming GOAAAAAAAAL which causes everyone to cover their ears to which Raccoony goodness gracious is he going super saiyan like Goku?
In the end the friends comment on how much fun the game was and how funny some of the fatalities were and say all we can do now is wait for MK1.
