Its been a while, but now its time for the next page of my Sonic Yugioh deck, mark 2! This page is full of villains, here are there effects:

Chaos 0: When this card is destroyed and sent to the graveyard, you can special summon it by paying 500 life points. If there are 2 or more cards with "chaos emerald" in their name in your graveyard you can tribute this card to special summon "chaos 2" from your hand or deck. (Chaos has regenerative powers, but isn't really very strong on his own)

Chaos 2: This card can not be summoned unless you have at least 2 cards that include "chaos emerald" in their card names in your graveyard. If there are 4 or more chaos emeralds in your graveyard you can tribute this monster to summon chaos 4 from your hand or deck. This card can not be destroyed in battle by a monster of level 5 or lower. (The addition of chaos emeralds makes Chaos stronger)

Chaos 4: This card can not be summoned unless you have at least 4 cards that include "chaos emerald" in their card names in your graveyard. If there are 6 or more chaos emeralds in your graveyard you can tribute this monster to summon chaos 6 from your hand or deck. If this card destroys a lv 3 or lower monster as a result of battle, it can attack once again in a row. (This phase of chaos has the ability to break itself apart and attack from multiple directions, hence the multiple attacks)

Chaos 6: This card can not be summoned unless you have at least 6 cards that include "chaos emerald" in their card names in your graveyard. If there are 7 chaos emeralds in your graveyard you can tribute this monster to summon perfect chaos from your hand or deck. This monster can attack directly by reducing its atk by half. (this form of chaos can transform itself for alternate attacks)

Perfect Chaos: This card can not be normal summoned or set, this card can only be special summoned by the effect of "chaos 6" If you do not have the 7 chaos emeralds in your graveyard, it is destroyed. When this card is summoned destroy all cards on your side of the field and in your hand except this card. This card can not declare an attack unless you discard 10 cards from the top of your deck. (Perfect Chaos destroys everything and can not be controlled, but he could end a duel by landing just one attack, even if your opponent has full life points)

Emerl: The original atk and def of this card become the atk and def of the monster it battles during damage calculation, when destroyed and sent to the graveyard, summon a small animal token (beast, earth, 0/0) 2 small animal tokens count as 1 monster for tributes. (Emerl's true power is in his ability to mimic his opponent, he's kinda like copycat, but his stats change depending on what he fights)

G-mel: exactly like Emerl, except its atk and def become the enemy monster's +100 and it is automatically destroyed unless Emerl is in your graveyard. (G-mel is a rebuilt Emerl, so he's like emerl plus one)

Biolizard: This card can not be summoned unless "space colony ark" (a field card I will make later) is in play. Discard cards from your hand to summon that many "Egg tokens" (reptile, dark, 0/0) This card can not be attacked so long as at least 1 egg token remains in play. when Space colony ark is destroyed while this card is out you can tribute this card to summon finalhazard from your hand or deck. (The very tough penultimate boss of SA2, and the ark's final guardian.)

Finalhazard: Can't be normal summoned or set, can't be special summoned except by biolizards effect, does the egg summoning trick...but if it remains on the field for 8 of your opponents turns, YOU WIN. (Finalhazard is a living asteroid, and if Supersonic and Supershadow fail to kill him in time he hits the earth and everyone dies, I chose 8 turn counts because it takes 8 hits to kill it.)

Oh yeah, thanks to hellbond for making the card templates!
