For Fun: Sumo Wrestler ability ideas

For these ideas, I'll refer to the champion as "Sumo" for ease. I thought it'd be fun to think of new ideas, and everyone can join in to brainstorm new ideas and new ways to bring those ideas to life.

Passives P1) When Sumo has been facing an opposing Champion for X seconds his muscles tense up, granting him bonus Armor for a short duration. This Passive has X seconds of cooldown, also the Armor granted increases based on level. P2) When Sumo stands still for a duration, he focuses his Willpower in a pause-able charge. While his Willpower is fully charged, his auto attacks and basic abilities deal extra on-hit damage, and his Willpower gradually decreases after a few seconds until he focuses his Willpower again. The less Willpower Sumo has, the less extra on-hit damage he deals; his Willpower starts to decrease on its own after X seconds he has been out of battle and is not charging Willpower.

Qs Q1) Sumo shoves a palm forward, throwing opponents hit away from his location a distance and inflicting a short Slow. If he shoves the opponents into terrain, he Stuns them instead. Q2) Sumo slams a palm downward, throwing opponents and trinkets away from a small AoE area. Trinkets affected by this ability are thrown farther but are not damaged or revealed.

Ws W1) Sumo charges a short distance in which he cannot turn, and stops when he reaches his destination or collides into terrain. Opponents he collides into are temporarily Stunned and brought with him until the ability ends, and are Slowed afterwards if he collides into terrain.

Es E1) Sumo lets out a battle cry, empowering his next auto attack. Empowered auto attacks under this effect stun opposing champions and steal Movement Speed for a short duration, and those affected by this cannot be Stunned for a short duration. E2) Sumo grabs an enemy Champion, and throws them in the direction he is facing. He can throw them after either a short duration or when he activates this ability again.

Rs R1) Sumo leaps into the air, choosing a location to land which deals True Damage in a radius to opponents hit. R2) Sumo slams his palms into the ground, creating a large crater that acts as a battle ring. Enemy Champions are slowed while in the crater. While Sumo is in the crater, Sumo leaps towards Champions X distance from him and has X% increased Attack Speed. Sumo cannot leap to an enemy Champion that has been leapt to already for a short duration. R2a) [Tying in with E2] If an enemy Champion is thrown from the crater by himself or an ally champion, they are stunned and take some continuous damage for a short duration.

I hope you all like these ideas. This is just for fun, but I thought I'd give it a go because I felt like it. Again, if you all have cool ideas to share you are free to do so! The theme is Sumo Wrestling though, so if your idea doesn't fit with the theme then it won't count. Thanks for reading, all!
