Congratulations!
You have been drafted into piloting a robot/mech/mecha of your choosing. The downside is that when you pick, you get shunted to that universe and must now contend with the in-universe scenarios that appear in the storyline. Bare minimum is you must spend one year there before you can be eligible to be sent back home.
So, what’s your choose? A Gundam perhaps? Or a tachcoma from Ghost in the Shell?
Perhaps a Zord from Power Rangers or even even an Ironman suit?
Where will the Plot Gods be sending you today?
