Tiger Nation Sk8tr

 Sk8tr for Tokidoki's Tiger Nation series 12 released in 2020. 

X-Pro Action Deck

Nameless female skateboarder from Soma's 1988 X-Pro Action Deck line, advertised as "Motorized Pull & Go." The figure can move forward or back on the deck to change the way they skate. 

 

Bart Simpson XVI

This Bart is from the 2004 Simpsons Danglers Collection Series 1 that would've been found as a capsule toy inside a Gacha Tomy vending machine. He's on a suction cup and then a thin wire holds him out and allows him to dangle.

 

Rabbid

Skateboarder from the 2011 Rabbids "sport collection." It's a little hard to see but he has bitten his board in half and has part of it in his mouth. I think this is the only figure like that (although not the only broken skateboard!).
