Mega Armewval

Pokédex Entry:

Due to being genetically modified in a lab, Mega Armewval's power knows no bounds and its body can handle the coldest of temperatures. Wherever it roams, destruction is sure to follow; scientists who created this Pokemon regretted the decision.

Used Lunala + Cresselia fusion to open a wormhole to another dimension, one without fusions so he could create his ideal world. Brought with him several other loyal fusions with him.
