My favorite is Slag. His name is Ignatius. Where I got that name? I loved this cartoon called Huntik: Secrets & Seekers a couple years back. (and i still love it). Ignatius is a fire type "Titan".

Perhaps next would be Talon which I named Solwing. (Again Huntik).

Abaddon, which I named Cavalier (Huntik again, a fighting titan that wielded two swords)
