Give examples of crazy champion concepts or abilities that Riot hasn't done

Here's mine

1. Buying a unique weapon in store (kinda like Viktor's staff) except it changes your autoattacks and maybe 1 ability to melee, medium range or long range champion.
2. A melee champion that is classified as a ranged champion. Nah not Gangplank. More like a melee champion whose autoattack animation is punching the air and an ghost like copy of himself does the attack on the target enemy in different directions.
3. A lazer ADC. A champion whose autoattack is a lazer that passes through units but stops at a target enemy champion. So a tank can block it, but it does mad damage if the unit stays on it for a long time. The lazer could use mana.
4. A wrestler champion that has abilities such as tag team suplex (wrestler + allied champion do a combo), summon wrestling ring (bounces enemy back like Azir ult),
5. A mage like AD champion- Something like AoE morgana W that does attack damage, long range Kog'Maw R's that apply on-hit effects, etc.
6. A champion with a pet that can be mounted.
7. A champion that can summon a portal anywhere on the map that an ally can click on to teleport to a location.
8. A portal that sucks up all damage thrown at it (like Yasuo's wall) except it can be reactivated to shoot back damage based on a base damage + number of spells it took(so a Galio-esque ult with its own ratio)
