Hi Alabi, I'm sure Monster Energy Drink would be interested in this one. The first thing a domain name has to do is it has to mean something and when I read this name I'm first seeing the M logo and then I'm thinking 'they are merging? With Who?'.
Unless you can conjure up a traditional Monster (werewolves, zombies, dracula ect..) that are Merging in some way I don't see this one selling, let alone being developed. Dream up a concept and make it happen then you may receive a few hundred bucks for it.
