X-Monster

The X-Monster is the boss of the second dungeon, Eagle's Tower.

He does not attack Marty directly, but instead jumps into his waiting jet. The jet has two attacks: charging directly at Marty and shooting a stream of "x"s that can knock him off of the tower. Since the tower only appears to have one story, it is doubtful that this would be very dangerous.

Smaller pieces of the X-monster are seen in Eagle's Tower and many other dungeons as minor enemies. They consist of a square made of four "x"s.

In one of the rare cases of a difficulty curve working properly in this game, he is slightly harder than the first boss.
