Deus ex Machina is the common term for a trope in which something not previously established (originally, a god) suddenly appears to resolve the plot. It's an old enough term that it's used here in the wiki. It's also surprisingly punnable, and that's half of what's going on here.
Tropes both named after Deus Ex Machina and conceptually related to the concept:
- Deus Angst Machina: Usually falls under "not conceptually related", but some examples are so egregious and heavy-handed that "only the writer can cause them more suffering now!" is in full action.
- Deus Ax Machina
- Deus ex Machina
- Deus ex Nukina
- Deus ex 'Scuse Me
- Deus Exit Machina
- Deus Sex Machina
- Diabolus ex Machina
- Diabolus ex Nihilo
- Parent ex Machina
