To Yu-Gi-Oh! fãs

I take it you're referring to Rex Raptor?^^ He was in some,I wouldn't say very many though..If you're talking about televisão Episode Wise His Debut was Episode in Episode 2 in the first season (I'm pretty sure it was Episode 2)he was also in Episode 3,11,12,58,151 to make easier he was in many of the Episodes in the 150 range like 152,153,154,155,etc. he also continued to episode 160,161,162,and he was probably in mais from those episodes on, I can guarantee he was in Episode 189 also. I just learned something he was in mais Episodes than I thought he was XD
I'm hoping this helps!^^
