I named them all:
Giga Spinax = Gigax (a combo of the two names)
Giga Allo = Big Al (based off the Allosaurus skeleton)
Giga Raja = Rajak (basically because it sounds cool!)
All so cute! I was battling with Gigax and thought that the way he looked on teh battle field was really cute so I drew him like that and then got all these! SOOOOooooO cute!
