Robo Bloog

From KeenWiki

A Robo Bloog is essentially a Cyborg Bloog. It's a Bloog with the mind of ten super-computers and the body of...well, 10, super-computers. The Robo Bloog can fire a huge ball of energy. If either Robo Bloog or the energy ball hits Commander Keen, that's it. Unfortunately, every time the Robo Bloog recharges his energy ball he adds one more shot to his attack. The more overcharged Robo Bloog becomes, the more erratic his behavior is. It'll be hard to time your attacks! If you manage to Defeat Robo Bloog, you'll get a Plasma Crystal.

This makes the Robo Bloog different from his normal Bloog compatriots in that he is rather intelligent and at first puts up quite a sophisticated defense. As he begins to overcharge and overheat however he becomes more unpredictable, finally exploding in a ball of flame.
