(1) People call it Tyhm's Heart because it has not much to do with Ninjas. And nobody wants to call it the Megaknight/Llamaman Heart. Plus, people can say "I'll go take out Tyhm's heart now" and have a good laugh
(2) Yes, the Bruges Bird should probably be renamed something different so as not to make a false reference to Bruges. He has his fame-to-noobs from a whole quest in Silmaria, which gives you the Cane of
Brugara, an early version of which he made himself. Though the name is as good as any.
(3) Metris by Kaimetsu. Konquence by Konidias. Need I say more?
(4) As far as the SS Bhala goes, I'd be surprised if Bhala had any hand in its construction...though the SS honds WAS made by honds.
(5) In short, don't be an egotist and love thy neighbor as thyself; preserve some semblance of an RP environment and come up with decent names. That goes for everyone from SSJ Vegetamon 1337 all the way to Stefan.
