>>58845261A few corrections
Gen I would only certainly be 1 reptile, depends on how you want to interpret Charmander's line, Charmander is a fire salamander, Charmeleon could be a fire chameleon, and Charizard is straight up a dragon... which doesn't exist... you could compare it to a reptile, but it would be a stretch...
And as
>>58845913 points out Gen XIII would be 2 mammals and 1 reptile, Sobble's design and Inteleon's name connects them very firmly to chameleons
