Have you heard!! They found a lot of prototype pokemon sprites from Pokemon Gold: beta! twitter.com/Seanbo124/status/1…
It's so interesting looking at all the pokemon that could have been! I want to draw more of them but started with the fire starters.

Here's my interpretation of the fire starter sprites.

// edit: also oops, didn't know their names have literally "bear" in them, so I based the last form on felines more, haha.. maybe I'll revisit these with more 'bear' in mind.

Also I want to say I'm glad these weren't picked (even though they're cute) because cyndaquil line is my favorite from all the starters!
