Starring: Chad James, Ben Singer
Blade VS Buffy Summers - S12-E10
Visible crew/equipment: After kicking Buffy away and she hits a smiley face on the wall, Blade jumps at her and kicks off the wall to kick her again. If you look closely at the left side of the screen where the bathroom mirror is, you can briefly see a camera for a couple of frames filming the action just on the edge of the frame. The lighting in the bathroom makes it sort of hard to see. (00:21:16)
Starscream VS Rainbow Dash - S1-E17
Continuity mistake: Rainbow Dash catches Star Scream in a tornado and spins him around so fast in his jet form that you see one of his wings break off and fall away. He plummets to the ground and transforms into his robot form and begins to beg for his life. He suddenly has both wings again at this point.
Nightwing VS Daredevil (DC VS Marvel) - S5-E12
Nightwing: What are you?
Daredevil: Better. (00:16:10)
Trivia: When Scorpion catches Ryu's fist, we get the first 2 hand-drawn shots in the history of the show. (00:12:00)
