Stygian Zinogre is pretty much the same as normal Zinogre except for the element change, the fact that its bolts home in on you, some unique moves like the charging while walking and that of 4U it combos pretty much anytime it attacks someone.

In other words, excactly like other subs and rares in that it has a bigger move pool, more hp and mabye some tweaks to the AI.
