This Trickster Custom Flash Villain looks excellent and was inspired by Mark Hamill’s earth 3 trickster from the Arrowverse.

The head is from Emmet Brown with repainted eyebrows, teeth and added wrinkles and lips. The Trench coat is paper, painted dark blue with magenta stripes. His legs are also painted with stripes and he has alternating coloured shoes. The torso is completely painted with a Purple shirt underneath and Silver tie. Finally, the TNT is just a red Technic ball with some text painted on.

Great job!
