Hmmm, hi, I'm trying to look for some old showcase avatars that appeared in this video....

In the video part it doesn't talk about the avatars name, but in the description part it says the name of the avatar's author and animation that appears in the video of the avatar part

First avatar I'm looking for in the video part is this one....

What appears in the video about the avatar is:
Kyuko! - Dragon Fight Animation

Second avatar I'm looking for is this one

What appears in the video about the avatar is:
Raivo - HellBringer
