Earth: Lifehack! Throws trash at opponent. Special ability, summons raccoons for a strong attack. Poison is a bonus effect. The more raccoons summoned, the stronger the poison bonus (stacking)

Water: Jack! Pure of heart, he has the ability to heal, or rather, to restore damage taken. Special ability, Umbrella in the Rain, forces an opponent to be your friend (you get to take & use one of their attack cards, but against a mutual enemy). Bonus: Acid Rain (poison all)

Ice: Chill! The attack variant of water, ability is Ice Wall, a strong defence. Special ability is Freeze Ray, which causes an opponent to freeze (skip a turn). Bonus effect: Hibernation, forces all other players to skip a turn, so effectively you get to draw twice & attack next.

Fire: Grill, of course! Attack, flamethrower, strong against 1 opponent. Special attack, Inferno, which attacks everyone a small amount (including yourself). Bonus: Pyromaniac, where you set the game on fire because you're a sore loser, and maybe the house burns down, too.

Air: Quiz. Skill: enhancement! Pairs with an attack or defense card to increase their stats. Special: Tornado, a strong attack against 1 opponent, weak against All other players (including self). Bonus: Breath of Life (get to (re)use anyone's discarded card)
