These characters are two of many unlock-able characters for a top-down view 2D mobile game.
The front facing stance is shown on the character select screen.
The game is a defense/survival game where projectiles are being launched at random at the player from off-screen. It’s the players objective to dodge or “swipe” them away.
The bottom views for each character are the ones seen while playing the game, one shown while standing or walking, the other while attacking or swiping at the projectiles.
The characters themselves are mostly cosmetic aside from their weapon; the sword can be used more often but the whip has a longer range.
