It seems that Aurumoth's Latin root will dictate the style of names for this stage. Well that makes it easier to get started, I suppose.
I like the direction Birkal took - he uses the root words, but then adds English touches just like Aurumoth itself combines the Latin and a common English word. They are also very evocative with 'tomb' and 'bee' respectively, it captures something essential about the two pre-evos.
To GlassAbsol and srk... I don't have much to comment on for your entries, other than the endings don't seem to fit as well, at least compared to Birkal's. Cupratle, for example, could be taken as one of many different things (Cuprum + botTLE, for example).
Here's my attempt at these:
1st Form: Cuprumini
Cuprum for Copper and Mini because it's so tiny - all cuteness implications are left to the readers/players.
2nd Form: Argenite
'Argen' from Argentum and 'nite' for 'knight' - this would've worked better if Kadew's art had won but I still feel the name is rather appropriate with the two wings it has looking somewhat like shields.
I welcome all feedback and I'll try to comment on others too. At any rate, good luck to everyone.
I'm a casual Smogoner that mostly frequents the forums - chances are you won't find me on IRC that often. If you want to talk shoot me a PM please, I'm not on every day but I'll eventually reply.
