Perhaps you can choose something you like?
If you think English is to boring you could always look up words in other languages.
A simple approach could also be adding some extra sound to the end of a word? Subtracting some letters could make a cool name too...
(Sorry these might be bad examples)
Red -> Reddu, Reddo, Ridu, Rd
Cloud -> Cld, Clou, Kludo
Taking parts of words and combining them could work as well...
(Forgive my weird word choices >A<)
Blue Cat -> Caue
Pretty Doll -> Prell
Rain Blanket -> Raiket
If I was to pick a more successful example, one of my friends had a nameless character and she told me that his main weapons were a syringe and a gun so I told her why not name him "Syun"? (Which I think sounds cool....)
Umm and I guess even more simpler choice could be adding a honorific at the end of a word/name?
Like Mi might sound a bit weird but add a -chan and suddenly Mi-chan sounds cool somehow doesn't it?
