You can get the same *effect* from normal martial arts attacks, yes, but that's not quite what I was suggesting. The above all fits in to the standard attack pattern:
<Name> <attack text> at <enemy name>!
<Name> hits the <randomly targeted bodypart> <hit count>.
(Optional) <Text describing what damage this did to enemy, e.g. teeth loss or death>
What I was suggesting was more along the lines of whole new type of attack:
<Name> attacks <enemy name> with <Signature move name>
<Signature move effect text>
<Text describing what the resulting damage does to the enemy>
So examples would be:
The Green Ninja attacks Police Officer with his Tree Hug!
Police Officer's chest and spine are crushed by the Liberal Power of the Love of Nature!
Police Officer slumps to the floor and dies.
The Green Ninja attacks Eminent Scientist with his Liberal Left Hook!
Eminent Scientist's head is punched clean off by the Liberal Fury behind the blow!
Eminent Scientist's body collapses as the head rolls away into the gutter.
The Green Ninja attacks News Anchor with his Rainbow Kick!
News Anchor is sent flying, hitting a nearby wall with an audible crack as his spine breaks!
News Anchor falls to the floor, paralysed.
The general idea is that this is a new semi-hidden type of powerful insta-hit, insta-kill (or disable, if that's what that signature move does) attack only available to top-level martial artists (and even then, not every attack they make is a signature move - say 1 in 4 or something?). This acts as an incentive to try and level up martial artists (for the powerful attacks) plus hopefully a little more humour can be injected into the fight text, rather than just combat mechanics.
Its just an idea, anyway, and may either be not really suitable for LCS, or too much of an annoyance to code.
