Lirieke: Megadeth. Psychotron.

Assassin in stealth
Assailant from Hell
Impervious to damage
Computer on-board
Engaged in a war
Non-stop combatant
Maybe not a mutant, maybe a man

Part bionic
And organic
Not a cyborg
Call him Psychotron

Burning inside
Godspeed in glide
Battle plan running
A killing machine
Just downright mean
And forever gunning
Maybe not a mutant, maybe a man

Target to destroy
Arms in employ
Full assault fire threat
Sensors indicate
You will terminate
Life systems disconnect

Psychotron
