Idea for a new champ

this isn't going to be a comprehensive skillset or anything, just a cool Idea I had while out in the rift. so this champion would be gravity based, as in he would work like planets and other celestial bodies, and would probably be a bruiser/initiate type so his passive would allow him to move faster, so long as he is moving at or near a 90 degree angle to any champion/turret/unit, moving faster as he approaches them, and slower moving away, just like orbital patterns. he would also gain extra speed based on how big the unit is, and how much health they have, so he would basically be able to dance circles around tanks like cho'gath and nautilus.

he would have an ability like a black hole that would make him channel and slow enemies moving away, speed them up moving towards, and when not moving it would drag them towards the epicentre, dealing continuous (if minor) damage. if any enemies are within a certain distance (the event horizon) when he finishes, they will take a lot more damage.

another skill could give him a speed boost and also make him unslowable for a while. I mean when was the last time we were able to stop an asteroid that wasn't evaporated upon entry?

another could allow him to teleport distances with no target after channeling, but the further away he choses to go, the larger the area he could possibly land in would be, the target circle would grow and he could be teleported anywhere in there at random, or it could be that he can aim it as it goes in and the circle shrinks, but enemies are given an indicator to try to avoid it. on landing he would cause an impact at the site in a small to medium area that would knock up enemies.

I can't think of another ability, but probably some kind of damage should people want to take him jungling.

I don't think he would need any dashes, the passive and some clever moving would be more than enough to catch up, but his weakness for such strong initiate would probably be he can't escape, as he's slowed when running away, and his cc only draws enemies to him.

anyway let me know what you guys think, this is my first champion idea and it seems like it would be really fun to play.
