Sensor sees energy level

could give more usage out of it, if you knew your enemy has only a little energy left.

I just use my brain for that...

Yes, and that won't stop.

Back to topic: reply to above post
this would actually stack with the extra sight sensor gives you, it would be useful before a battle, allowing you to choose to engage or not.
e.g.

FOR EXAMPLE:
LITTLE_APPLE HAS SENSOR + SHIELD W/SOME ENERGY, AND CAN SEE TAZ HAS VERY LITTLE ENERGY. TAZ DECIDES, I WILL ATTACK (This is how I think), THE_APPLE LAUGHS BECAUSE HE KNOWS TAZ CANNOT TURBO OR SHIELD AWAY OR SUSTAIN ANYTHING BESIDES PHASER (WHICH IS ADMITTEDLY STRONG NOW, BUT I THINK IT'S NERFED IN 019). OTHERWISE HE WOULD TOTALLY RUN AWAY. totally. really. No??
APPLE WINS.
