Tbh the ask Courtney just got reminded me of something?? I kinda headcanon that unstable mega evolved Pokemon behave similarly to shadow Pokemon in hyper mode. For those that didn’t play Colosseum, hyper mode was achieved when a shadow Pokemon would “enter a fevered pitch” during battle and:
- It may disobey and use another move instead (usually Shadow Rush).
- It may turn and attack its teammate instead.
- It may attempt to use its item, even if it isn’t holding one.
- It may hurt itself, as if it were confused.
- It may actually attack its Trainer or the opposing Trainer.
- It may use the chosen move normally and obediently, though this is very rare.
- If it is in the middle of a two-turn move such as Fly, it may leave Hyper Mode on its own, though this is extremely rare.
- It may do nothing at all.
- It may return to its Poké Ball, even if it’s under the effect of Mean Look.
