The CRUSTACEAN KING! - He may be slow...BUT he has some pretty sweet abilities.
At first glance this guy is easily going to be the last monster to be able to attack in every game with a Speed of 1. However, once he is leveled up I believe you will see that he is quite useful. He has some armor which is important right off the bat, but his abilities are GROUP TEAM abilities.
Group Heal and Protect.
Group Heal will give every teemmate a healing boost after every round.
Protect give every teammate an automatic armor boost from this King.
I believe this guy is a VERY UNDERRATED Monster just looking at the stats.
