H-11R

The second H-series and final Robot-type monster, this creature is considerably tougher than its predecessor, even incorporating the Wind resistance found in the later S-series robots. Despite this, it's equal in power to both the weakest S-series monster and the strongest K-series monster, so you really shouldn't have much problem at this point in the game in defeating them. Paralyze them and blast them with Song Magic once it has been charged for long enough.
