In Sonic RPG Episode the 8th, Sonic the Hedgehog and Shadow start out by doing battle with Seelkadoom. Sonic RPG Eps 8 is the first of the sonic games to feature a new innovative menu system that displays all of the info you need for each attack/skill. Do not let your HP fall below 1900 or Seelkadoom could take you out in one shot! Sonic & Shadow have Overlimits and can use the ability if both of their gauges fill up.
