While I was playing Dominion with Skarner it occurred to me that it would be fun to have more animal type champions. So this is what I think
Octupusish Champion: This champion would be a tank, with lots of slows. For example it will grab the enemy with its tentacles and do damage. Another attack would be after a short delay it shoots tentacles out of the ground to hold the target in place.
Eagle or Phoenix Champion: The eagle would be more of a support player with 2 wind moves for attack and 2 for support. For example one could be a tailwind which significantly boost the speed and attack speed of all allied champions nearby. An ultimate would be Tornado, it does massive damage to a champion caught inside it and sucks in ,damages and slows enemies outside it.
The Phoenix would be the twin version of Anivia but would have crazy powerful fire attacks. That does damage over time. An ultimate attack I thought of would be Magma Storm. Creates 4 Flaming Tornadoes that spins around an enemy champion and traps the enemy champion inside the middle of them and does extreme damage over time.
Shark like Champion: Kinda like Fizz and Werewik combined. It's a fighter champion. One passive attack would give this champion high movement speed, attack speed, and + 75 attack, when he smells Champion under 50% health. An ultimate would be to summon an army of sharks to attack enemies(For 1-2 min). This ultimate can also do one of two attacks Frenzy Feed or Shark Torpedo but after using one of the moves the sharks disappear
Frenzy Feed: All the sharks rush at the enemy and feasts on them dealing ETREME damage to the target while giving the user health back.( Not sure how much health maybe between 300-657)
Shark Torpedo: All the sharks charge at the target and smash into the target at full power trying to severly cripple and kill the target, this move also damages the the user of this move.
Eel Champion: This champion has LOTS of stuns. All of its attacks do stuns. This champions passive ability when attacked by a melee enemy stuns them for 1.5 seconds when they try to attack.
This champions ultimate(obvious choice it uses electricity) sends down lightining bolts that stuns and deals damage to enemies in the area.(More effective if you are fighting one champion)
Another move that this champion has, charges its attacks up and then on the next use of this move this champions charges with all the energy it charged up at the target with lighting quick and smashes into the target knocking the enemy back.
