Solid Snake vs. Umbreon. Pretty evenly matched, actually. Umbreon is very defensive so he can't kill Snake instantly or do much at all, but that also means Snake's weapons won't do much damage and Umbreon can heal with Moonlight or use Snatch to steal the effects of Rations or other items. More of a stalemate, really. --- Other M is the One More Day of Metroid
