There's also the purple one which does have a 22 second cooldown. So like a power-free, missile-free Ion Bomb.
Also, I like the idea you can force a surrender from the enemy, but I dunno, I think they need to be more Doctor-like. Basically if they choose to surrender, you have to take one of the offers (or push for more and then they can refuse).
The Doctor doesn't say "I don't like your surrender offer, so I'll now destroy you" it's more like "I don't like your offer but I won't destroy you because killing is wrong. Hey Companion, what are you doing with that device that can kill the monster? Oh, you killed them. Oh well, badminton anyone? Alonsie!"
Then again, who am I kidding, the Doctor just kills people or lets them die because he doesn't like how they treated their companions relatives.
"Surrender Rebel ship!"
"Doctor! We surrender, please don't kill us! We worship you and your blue box!"
"Hey Doctor, that Rebel insulted me mum back in Federation space!"
