Well it's definately not from R. It's not 
Gigarosu from episode 52. I've got a cel of all 
the Cardians from The Doom Tree series, except 
that crazy hornet lady that Ail & Ann had no 
control over. I listed the link to my Cardian 
collection to show you the examples of all of the 
rest of the Cardians.

The only episodes that I haven't seen of SM are 
the specials. Is it from there? Unless it's from 
Super S the last episodes of the season which I 
have not seen yet. (*waiting on last Pegasus DVD 
to be released)

Here's a link to my site aswell, just incase you 
come across another monster of the day you need 
to look up.

Good Luck!

Sincerely, Beans  ^_~
