Almost Mecha-Lion

The Almost Mecha-Lion is a boss from Mother 3, appearing in Chapter 7. While Lucas and Boney were looking for Salsa and his girlfriend in the Chimera Laboratory, they bumped into the Almost Mecha-Lion, a Chimera with only a part of his face is flesh. However, they do not have to win the battle to progess.

If the battle is won, the lion tries to attack Lucas and his dog again. However, he is knocked by a Clayman. The same happens if the battle is lost.

Description from Battle Memory
"The only non-mechanical part is a portion of its face. Only eats raw meat soaked in machine oil."
